¶ 1 After a jury trial, Angel Diaz was convicted of first degree burglary, attempted armed robbery, and aggravated assault. On appeal, relying on the reporter’s transcript reflecting that only eleven jurors were polled following return of the verdicts, Diaz successfully аrgued that his right to a twelve-person jury had been violated. We disagree and conclude that Diaz failed to establish any legal error. Accordingly, we vacate both the opinion and supplemental opinion below and affirm his convictions.

¶ 2 On the first day of Diaz’s trial, the trial court empanelled fifteen jurors. Two days later, after closing arguments, three jurors were selected as alternates and excused. The trial court instructed the remaining jurors that their verdicts “must be unanimous” and that “[a]fl 12 of you must agree on a verdiсt.” The jurors began deliberating that afternoon.
¶3 The jurors resumed deliberations the next morning under the charge of the court’s bailiff, and that afternoon the foreperson informed the court that the jury had reached its verdicts. After the jurors were brought into the courtroom, the trial court stated, “[t]he record may show the presence of the jury.” The clerk then read the verdicts from the verdict forms, which the jury foreperson had signed on behalf of “the Jury, duly impaneled and sworn.” The jury found Diaz guilty of the aforementioned charges аnd not guilty of several others.
¶4 After reading the verdicts, the clerk asked: “Members of the Jury, are these the verdicts and the verdicts of each of you?” The jurors, in unison, answered “[y]es.” The court then asked the clerk to poll the jurors by number, and each responding juror confirmed the verdicts.
¶ 5 The reporter’s transcript reflects that only eleven jurors were asked and responded to the polling question. Specifically, the transcript omits any mention of juror number six, one of the twelve jurors designated to serve and decidе the case. Diaz’s counsel did not object to any aspect of the jury-polling process or question whether all twelve jurors were present or responded affirmatively when polled. Nor does the record reflect that the prosecutor, thе bailiff, the clerk, the other jurors, or the judge noticed or mentioned a juror’s absence or failure to respond to the poll.
¶ 6 Diaz appealed, claiming a violation of his right to a twelve-person jury. In a split

¶ 7 It is uncontested that Diaz was entitled to a twelve-person jury because he faced a possible sentence of thirty years or more in prison.

¶ 8 Judge Howard dissented, stating “[t]he flaw in Diaz’s argument is that the transcript of the polling proves only a defect in the polling, or possibly in the transcript, but it does not reflect a defect in the deliberations.”

at 215 ¶ 19,
¶ 9 About one week after the court of appeals issued its opinion, the court reporter filed a “corrected transcript,” showing that juror number six had answered “yes” when polled. In an accompanying affidavit, the reporter averred that shе had mistakenly failed to transcribe the polling of juror number six from her notes. The State moved for reconsideration, urging the court to vacate its prior opinion and affirm Diaz’s convictions because twelve jurors had, in fact, decided his guilt. In a supplementаl opinion, the court declined to reconsider its ruling and denied the State’s belated motion to supplement the record on appeal, concluding that “any attempt to amend the record at this juncture is untimely.”
Diaz,
¶ 10 We granted review to address a recurring issue of statewide importance that has produced conflicting results in our appellate court. 2 We have jurisdiction pursuant to Article 6, Section 5(3) of the Arizona Constitution and A.R.S. § 12-120.24 (2003).

¶ 11 “Alleged trial court error in criminal cases may be subject to one of three standards of review: structural error, harmless error, or fundamental error.”
State v. Valverde,
¶ 12 This ease is somewhat unusual in that it involves a dispute about what actually happened in the trial court rather than whether an undisputed trial record establishes legal error. Diaz essentially asks us to determine what occurred in the trial court by accepting his interpretation of the original jury-poll transcript and finding that what occurred was error of fundamental proportion. The factual predicate for Diaz’s legal argument, however, is lacking. Diaz has failed to meet his burden of showing that the alleged error occurred and, therefore, we need not determine the applicable standard of review.
¶ 13 In evaluating Diaz’s claim of error, we review the entire record.
See State v. Thomas,
¶ 14 Applying these principles, we find this record does not show that “only eleven jurors participated in the determination of [Diaz’s] guilt.”
Diaz,
¶ 15 The omission of any mention of juror number six from the reрorter’s original transcript of the poll is certainly irregular and likely reflects some sort of mistake. Diaz argues it reflects the absence of a juror, while the State contends it merely suggests one of several other, more likely, scenarios: (1) a polling error (i.e., juror number six, though present, was skipped over without anyone noticing the mistake); (2) a recording error, caused by the reporter’s failure to hear the question to and response from juror number six; or (3) a transcription error, caused by the reportеr’s failure to transcribe from her notes the polling of juror number six.
¶ 16 As Judge Howard correctly noted, however, Diaz’s proffered theory is unfounded because “one juror’s omission from the poll does not prove that only eleven jurors deliberated.”
Diaz,
¶ 17 When the uncorrected record is considered as a whole, the prospects that a juror inexplicably and without notice failed to appear on the final day when deliberations resumed or simply vanished when the jury reentered the courtroom to return its verdicts are the least likely explanations for why the reporter’s transcript reflects the polling of only eleven jurors.
See Cabberiza v. Moore,
¶ 18 Finally, we note that this issue could have been resolved at a much earlier stage by applying Arizona Rule of Criminal Procedure 31.8(h). 4 Once the State learned of Diaz’s contention on appeal and his reliance on the reporter’s transcript to support it, the State could and should have asked the appellate court to employ that rule to clarify what actually occurred during the polling process. That procedure wоuld have better served the goals of timely administering justice and searching for the truth. We do not fault the court of appeals for rejecting the State’s untimely efforts to supplement the record after receiving that court’s opinion because the рarties bear primary responsibility for assuring the accuracy of the record on appeal. But appellate courts may sua sponte stay an appeal and remand the case to the superior court for reconsideration or clarification of the record under Rule 31.8(h). We encourage parties as well as trial and appellate courts to use this rule in appropriate circumstances to avoid delay and waste of time and resources.
IV
¶ 19 We hold that Diaz failеd to establish any error, fundamental or otherwise, relating to the number of jurors who determined his guilt. Accordingly, we vacate the court of appeals’ opinions and affirm Diaz’s convictions and sentences.
Notes
. In
State
v.
Soliz,
. See, e.g., State v. Smith,
1 CA-CR 08-0864,
. We now know, of course, that twelve jurors in fact deliberated and determined Diaz's guilt; thus, the error he complains of did not occur. We do not consider the corrected transcript that establishes those facts, however, because the court of appeals denied the State's untimely attempt tо supplement the record and we did not grant review of that issue.
. Rule 31.8(h) provides in part: "If any controversy arises as to whether the record discloses what actually occurred in the trial court, the difference shall be submitted to and settled by the trial court.” Pursuant to the rule, an appellate court, "on motion or on its own initiative, may direct that [any] omission or misstatement [in the record] be corrected, and if necessary that a supplemental record be certified and transmitted.” The rule "is intended to prevent major delays and confusion when mistakes or omissions occur.” Ariz. R.Crim. P. 31.8(h) cmt.
