OPINION
¶ 1 After a jury trial, appellant Javier Fim-bres was convicted of three counts of forgery of a ei’edit card, one count of theft of items with a market value of more than $2,000, three counts of computer tampering, and one count of fraudulent scheme and artifice. He was sentenced to multiple concurrent prison terms, the longest of which was 4.5 years. On appeal, Fimbres argues the state presented insufficient evidence to support several of his convictions. He also contends his right to due process was violated because the trial court instructed the jury on an uncharged offense of credit card forgery. For the following reasons, we affirm.
Facts
¶ 2 “We view the facts in the light most favorable to sustaining the convictions.”
State v. Robles,
¶ 3 Fimbres was apprehended on July 13, 2007. At trial, the state presented evidence that unauthorized transactions had been made on several victims’ credit card and debit accounts. Surveillance cameras from the stores showed Fimbres using the gift cards. Fimbres also admitted having made the purchases with the cards but claimed he *297 did not know the cards had been altered. The jury found Fimbres guilty of all charges.
Insufficiency of the Evidence
¶ 4 Fimbres argues the evidence was insufficient to support his convictions for fraudulent scheme and artifice, computer tampering, and two counts of credit card forgery. He also contends insufficient evidence was presented to prove that he was guilty of theft of items valued at $2,000 or more.
1
When considering claims of insufficient evidence, “we view the evidence in the light most favorable to sustaining the verdict and reverse only if no substantial evidence supports the conviction.”
State v. Pena,
Fraudulent Scheme and Artifice Conviction
¶ 5 Fimbres first cоntends the evidence was insufficient to support his conviction for fraudulent scheme and artifice because the state failed to show that he “obtained a benefit by means of a false pretense or representation.” To convict a defendant of a fraudulent scheme or artifice pursuant to A.R.S. § 13-2310, the state must prove, inter alia, that the defendant obtained a benefit “by means of false or fraudulent pretenses, representations, promises or material omissions.” § 13-2310(A);
see also State v. Johnson,
¶ 6 Fimbres argues there was “no evidence thаt he created any pretense, misrepresented himself, or. concealed anything from the [store] cashiers.” In support of this argument, Fimbres states that he presented his “Arizona Identification Card” to the store cashiers when requested and “signed his own name when prompted” by the store’s credit systems.
¶ 7 But evidence was presented from which the jury could conclude that Fimbres did obtain a benefit through misrepresentation or false pretense. Fimbres testified that he had used what appeared to be valid store gift cards to purchase goods from the stores. By doing so, he represented that the cards were valid. And a police officer testified that the cards were not valid and instead had been illegally altered to correspond to various credit card and debit accounts that did not belong to Fimbres. Accordingly, there was sufficient evidence from which the jury could infer Fimbres had falsely represented that his store gift cards were legitimate rather than illegally altered.
¶ 8 Fimbres claims, however, that he thought the cards were valid and therefore did not misrepresent that he was using legitimate gift cards. But this is not an issue of sufficiency of the evidence, but of Fimbres’s credibility. “That was a matter for the jury to resolve, and we will not disturb its conclusions.”
State v. Lee,
¶ 9 The two cases Fimbres cites in support of his argument do not require a different conclusion. In
Johnson,
¶ 10 At oral argument, Fimbres also emphasized that his conduct was covered by A.R.S. § 13-2105, fraudulent use of a credit card, a misdemeanor or a class five or six felony, and argued that the legislature therefore intended that he be prosecuted and punished under this more lenient statute rather than § 13-2310, which punishes violations as a class two felony. But he was unable to cite any authority supporting his position and we are not aware of any. There is authority, however, that a crime may be made punishable under different statutes. See A.R.S. § 13-116 (act punishable in different ways by different sections of thе laws may be punished under both, but sentences must be concurrent). Accordingly, the existence of two statutes criminalizing the same conduct does not evidence a legislative intent that the offense only be punished under the more lenient of the two.
Computer Tampering Convictions
¶ 11 Fimbres also argues that the state presented insufficient evidence to support his convictions for computer tampering pursuant to AR.S. § 13-2316. He contends that the plain meaning of § 13-2316 demonstrates the statute was enacted solely to criminalize “computer hacking” and does not encompass other computer-related conduct such as swiping through a credit card reader store gift cards enсoded with illegally obtained credit and debit card numbers. Fimbres therefore claims that the evidence presented cannot possibly support a computer-tampering conviction.
¶ 12 When construing a statute, “[o]ur task ... is to fulfill the intent of the legislature that wrote it.”
State v. Williams,
¶ 13 The plain meaning of § 13-2316 is clear and unambiguous and demonstrates that the statute is not limited to the crime of computer hacking. Section 13-2316(A) provides:
A person who acts without authority or who exceeds authorization of use commits computer tampering by ... [accessing, altering, damaging or destroying any computer, computer system or network, or any part of a computer, computer system or network, with the intent to devise or execute any scheme or artifice to defraud nr deceive, or to control property or services by means of false or fraudulent pretenses, representations or promises.
“Accessing” a computer system with intent to defraud is a far broader prohibition than “computer hacking.” And Fimbres’s actions here fall within that prohibition.
¶ 14 For a store’s credit card reader to charge or debit customers’ accounts, the reader must necessarily be linked to the store’s computer system or network. A defendant who swipes gift cards bearing illegally obtained credit and debit card numbers in a store credit card reader therefore accesses the store’s computer system or network with the intent to execute a scheme to defraud.
See State v. Gillies,
¶ 15 Fimbres argues, however, that even if § 13-2316 “encompasses the ... use of the card swiping machine,” the evidence was still insufficient to support his convictions on counts four and five because no witness testified that his use of the cards was unauthorized on the dates alleged in these counts. Circumstantial evidence was presented, however, from which the jury could conclude that Fimbres used a store computer system to make unauthorized charges to a Visa card account on July 13, 2007, as alleged in count five of the indictment.
See Landrigan,
¶ 16 Substantial evidence was also presented to support Fimbres’s conviction for computer tampering on June 1, 2007 — as alleged in count four. A store security specialist testified that Fimbres used MasterCard number “9221” to purchase a video game system for $648.59 on June 1. And victim A.M. testified that she incurred an unauthorized charge of $648.59 on her MasterCard in early June.
¶ 17 The evidence also showed that Fim-bres used multiple altered cards on several occasions over the course of several months and, if one was refused, simply offered another. And other victims besides A.M. testified that their cards were used without authorization and the video game system purchased on this occasion was the same type of merchandise purchased on several other occasions.
¶ 18 Additionally, as the state noted at oral argument in this court, this evidence should be viewed in light of the other evidence at trial, including Fimbres’s own testimony. Fimbres expressly admitted in opening and closing statements through counsel that the cards he presented were altered and used without authorizаtion; he only contested his knowledge of the alteration. Although arguments of counsel are not evidence,
State v. Grounds,
¶ 19 A.M. also testified, however, that her MasterCard was number “3704” rather than “9221.” Although the difference in credit card numbers in this count is troublesome, and the state should have cleared up this obvious deficiency in its ease, the time period and amount matched exactly and the jury could have found that either the victim or the security specialist mis-spoke.
See State v. Dugan,
Forgery of a Credit Card
¶ 20 Fimbres next contends the state presented insufficient evidence to support his convictions for forgery of a credit card in counts seven and eight. As relevant here, a defendant commits forgery of a credit card if he or she is not the cardholder and, with the intent to defraud, “signs the name of any actual or fictitious person to a credit card or instrument for the payment of money which evidences a credit card transaction” or “utters” a credit card without express authorization from an issuer to do so. A.R.S. § 13-2104(A)(1), (2).
¶ 21 Fimbres testified that he “signed for” every purchase he made using the altered gift cards. To make a purchase with an altered card, Fimbres necessarily would have had to present, or utter, the card. And although he denied having made the purchases with an intent to defraud, we defer to the jury’s assessment of his credibility and the weight to bе given to his testimony.
See Cid,
¶ 22 Fimbres also argues, however, that “in counts seven and eight there was insufficient evidence that the card[s he] used belonged to anyone else or that [he] was not authorized to use those cards.” Count eight refers to the same transaction alleged in count five as computer tampering, which occurred on July 13, 2007. And count seven refers to the same transaction alleged in count four as computer tampering, which occurred on June 1, 2007. We have already explained that a reasonable jury could conclude that Fimbres was not the holder of the Visa card he used in making unauthorized charges to S.W.’s account on July 13, as alleged in count eight. And we have also explained that a reasonable jury could conclude Fimbres was not the holder of the MasterCard he used in making unauthorized charges on June 1, as alleged in count seven. Moreover, Fimbres testified he had presented a card and subsequently signed for each transaction, including transactions on July 13 and June 1. We therefore affirm his convictions on these counts.
Theft Convictions
¶ 23 Fimbres finally argues that thе state presented insufficient evidence to prove he was guilty of theft of items valued at $2,000 or more. Section 13-1802(E), A.R.S., provides as follows:
Theft of property or services with a value of two thousand dollars or more but less than three thousand dollars is a class 5 felony. Theft of property or services with a value of one thousand dollars or more but less than two thousand dollars is a class 6 felony.
With respect to a theft conviction, if the record does not contain substantial evidence to show the fair market value of the property stolen, there is insufficient evidence to support the theft classification, and fundamental error results.
Stroud,
¶24 Fimbres was convicted of theft of property valued at more than $2,000 — a class five felony. At trial, the state alleged that Fimbres’s transactions in aggregate totaled $2,494.99. Fimbres argues, however, that insufficient evidence was presented to prove that two of the transactions — $648.59 on June 1 and $582.43 on July 13 — were unauthorized. He therefore claims that both $648.59 and $582.43 should be subtracted from the state’s alleged total of $2,494.99— equaling $1,263.97, a class six rather than class five felony.
¶ 25 We have already explained, however, that sufficient evidence was presented to prove that Fimbres’s June 1 and July 13 transactions were unauthorized. The same analysis applies to the theft conviction. We *301 therefore affirm Fimbres’s conviction for theft of items valued at $2,000 or more.
Validity of Convictions for Credit Card Forgery
¶26 Fimbres also claims that his convictions for credit card forgery violate his light to due process because the superior court lacked subject matter jurisdiction over them. Citing
State v. Mikels,
¶ 27 We review this issue de novo.
See State v. Flores,
f 28 In
State v. Smith,
¶ 29 More recent authority, however, calls into question whether this issue now would be treated as one of subject matter jurisdiction.
See State v. Maldonado,
No. 1 CA-CR 07-0837, ¶ 13,
¶ 30 Smith did not discuss article VI in reaching its decision and instead relied upon article II, § 30. Article II is entitled “Declaration of Rights.” Unlike articlе VI, article II, § 30 does not establish the trial court’s jurisdiction and instead states that “[n]o person shall be prosecuted criminally in any court of record for felony or misdemean- or, otherwise than by information or indictment; no person shall be prosecuted for felony by information without having had a preliminary hearing before a magistrate or having waived such preliminary examination.” Thus, the placement of the section and its plain language seem to confer personal rights on the defendant rather than to limit the subject matter jurisdiction of the court.
¶ 31 Furthermore, article II, § 30 allows a defendant to waive a preliminary hearing, whereas subject matter jurisdiction can neither be waived nor conferred by the parties.
See Flores,
¶ 32 In any event, the original indictment here undoubtedly states the elements of a felony offense — credit card forgery under § 13-2104(A)(2). Consequently, the original indictment invoked the subject matter jurisdiction of the trial court.
See Buckley,
¶ 33 Fimbres’s argument that the trial court lacked subject matter jurisdiction is therefоre necessarily limited to the validity of the court’s amendment of the indictment. But, as we have already explained, subject matter jurisdiction is established when the indictment is filed,
see Buckley,
¶ 34 Fimbres contends that being convicted of a unindicted offense under subsection A(l) violated his due process rights, constituting either structural or fundamental error. That occurred, he claims, because the trial court instructed the jury on both subsections.
¶ 35 In
Valverde,
our supreme court explained the differences between structural error and fundamental error review.
¶ 36 Fimbres claims the error was structural because it “permeated and tainted the entire trial framework.” But Fimbres neglects to explain how such permeation and taint occurred. Further Fimbres’s alleged error does not fall within the same category of cases that have been found to be structural error.
See Valverde,
¶ 37 As we have already explained, prejudice is not presumed under this standard of review.
See Valverde,
¶ 38 We first review the trial court’s instructions amending Fimbres’s indictment for error. Pursuant to Rule 13.5(b), a trial court may amend an indictment to “correct mistakes of fact or remedy formal or technical defects.” An amendment corrects a formal or technical defect, and is therefоre permissible, if it does not change “the nature of the offense charged or prejudice[ ] the defendant in any way.”
State v. Sanders,
¶ 39 In
Sanders,
the defendant was initially indicted for assault of a pólice officer pursuant to A.R.S. § 13-1203(A)(3).
¶ 40 Here, the initial indictment charged Fimbres with credit card forgery pursuant to § 13-2104(A)(2), which requires that the defendant sign the name of any person for a purchasе on a credit card of which he is not the holder. But, as the tidal court stated, the amended indictment permitted the jury to find Fimbres guilty of altering or manufacturing a credit card under an accomplice theory of liability. Any manufacturing or alteration would have necessarily occurred at a distinctly different time and place than signing for a purchase and would therefore change the original indictment’s factual allegations. And even if the acts Fimbres committed establish accomplice liability in the manufacturing of the altered cards, that change would be improper. Accordingly, as in Sanders, the court erred in amending Fimbres’s indictment because the amendment changed the nature of the offense originally charged. 7
¶ 41 Even though Fimbres has shown the trial court erred, he still has the burden of showing such error to be fundamental.
See Henderson,
¶ 42 Furthermore, even if Fimbres could have shown the trial court’s jury instructions to be fundamental error, he still has the burden of showing resulting prejudice.
Id.
¶ 22. Fimbres relies on
Sanders,
however, in which Division One stated that, if an amendment to an indictment changes the nature of the offense originally charged, “prejudice inheres in the amendment and is conclusively presumed.”
¶ 43 In determining whether Fimbres has shown prejudice, we note he did not request an interrogatory verdict on the credit card forgery counts, which would have required the jury to specify which subsection of § 13-2104(A) it found he had violated. Therefore, Fimbres cannot demonstrate that the jury found him guilty under § 13-2104(A)(1) and cannot meet his burden of showing prejudice. Additionally, overwhelming еvidence supports the conclusion that Fimbres committed credit card forgery under the subsection charged in the indictment.
See
§ 13-2104(A)(2);
State v. Gallegos,
¶ 44 This case is akin to
State v. Delgado,
¶ 45 In any event, the record here demonstrates that Fimbres was found guilty as indicted. The jury’s verdict on count six states that it found Fimbres “guilty of the offense of forgery of a credit card
... as alleged in Count Six of the Indictment.”
(Emphasis added.) The verdict on count eight similarly states the jury found Fimbres guilty of forgery of a credit card
“as alleged in Count Eight of the Indictment.”
(Emphasis added.) Both the prosecutor in closing argument and the trial court in instructing the jury made clear that there are two separate subsections — (A)(1) and (A)(2) — of the credit card forgery statute. And each juror was provided with a copy of the indictment that showed Fimbres was charged under § 13-2104(A)(2) and the charge mirrored its language. Because the jurors were instructed that § 13-2104 has two parts, because each juror was given a copy of the indictment showing that Fimbres was charged only under subsection (A)(2), and because the jury’s verdicts stated it found Fimbres guilty “as alleged ... in ... the indictment,” the record supports the conclusion that Fim-bres was found guilty of credit card forgery pursuant to the subsection charged in the'indictment. Additionally, the prosecutor did not emphasize or seek conviction under § 13-2104(A)(1).
See Valverde,
220 Ariz. ¶¶ 16-17,
Conclusion
¶ 46 In light of the foregoing, we conclude that sufficient evidence supported Fimbres’s convictions. We also conclude that the trial court’s jury instructions did not violate Fim-bres’s right to due process. We therefore affirm Fimbres’s convictions and sentences.
Notes
. Although Fimbres appears to have moved for judgment of acquittal on some of the counts he now challenges, he did not make a motion on all of them. Any claim on those omitted counts is therefore forfeited absent fundamental error.
See State v. Stroud,
. Although Fimbres acknowledges the holding in
Gillies,
he contends
Gillies
was “wrongly decided" and is therefore inapplicable. He also argues that
Gillies
was published simply because it was a death penalty case and claims that, "if the supreme court were to actually accept review on th[e issue in
Gillies
] and subject it to meaningful analysis, its decision would be different.” We reject Fimbres's suggestion that noncapital issues in capital cases do not receive “meaningful analysis.” Furthermore, ”[t]his court is bound by the decisions of the supreme court and has 'no authority to overrule, modify, or disrеgard them.' ”
State v. Miranda,
. Specifically, Fimbres was asked “you knew ..., the gift cards you were presenting, that they were false. Is that true?” He replied, “No, I did not know it.”
. Although Fimbres apparently objected to the instruction’s including language about manufacturing and altering a credit card, he did not object based on the lack of such language in the indictment or an alleged lack of subject matter jurisdiction.
. The court in
Flores,
. Fimbres claims that this argument was preserved, but his objection below was limited to the wording of the instruction and was not based on any variance between the indictment and the instruction. The error is therefore subject to either fundamental or structural error review.
See Valverde,
. The parties have not argued and we do not decide today whether § 13 — 2104(A)(1) and (2) describe different crimes or a unitary crime under
State v. Forrester,
