MEMORANDUM OPINION
This is a suit for breach of a lease agreement. TA/Sugar Land-ECO, Ltd. (TASL) entered into a lease agreement with ECO Resources, Inc. (ECO), a firm that provides water and wastewater treatment services to various municipalities. TASL agreed to build a laboratory and office building to suit ECO’s needs, and ECO agreed to rent the building for twenty-five years. TASL hired Terramark as the general contractor for the construction contract. After ECO had moved into the building, TASL assigned its interest in the lease to Ashford Partners, Ltd. (Ashford).
When foundation problems appeared, ECO contacted Ashford. Ashford undertook repair efforts and sued Terramark, the general contractor, for, among other things, breach of its construction contract. Terramark joined ECO as a third-party defendant. After Ashford brought a claim for declaratory relief against ECO, ECO counterclaimed for breach of the lease.
This appeal arises out the trial court’s entry of judgment based on the jury findings in favor of ECO on its counterclaim. In seeking reversal, Ashford contends that the trial court erred in entering judgment on the jury finding that it failed to comply with the lease and in awarding ECO its attorney’s fees because ECO and Ashford were not parties to the lease at the time of the breach. Ashford further contends that the trial court erred in denying its motion for judgment notwithstanding the verdict (jnov) because the evidence proves, as a matter of law, that ECO waived or is estopped from pursuing its breach of con *303 tract claim. 1 Finally, Ashford contends that the trial court submitted an incorrect measure of damages to the jury. We conclude that (1) an enforceable contract existed between the parties at the time of the breach, (2) the trial court correctly denied Ashford’s motion for jnov, and (3) the trial court submitted a correct measure of damages. We therefore affirm.
Background
Lease terms
The lease contemplated that TASL would oversee construction of the building and build out the interior according to space plans and specifications supplied by ECO, referred to as “Tenant Finish Work.” These and other tasks were time-sensitive. Exhibit D to the lease, entitled “Schedule of Critical Dates,” set forth “critical dates relating to Lessor and Lessee’s respective obligations with respect to construction of the Tenant Finish Work for the Premises.”
The schedule specified that the Lessor is responsible for a November 1, 2001 “Estimated Completion Date.” The significance of that date stemmed from the fact that the lease would not come into effect until the building was “substantially completed” and TASL had obtained a certificate of occupancy. The lease defined “substantially completed” to mean that construction had been completed “in accordance with the Plan subject only to completion of minor punch card items.”
Under the lease, TASL agreed to notify ECO “in writing at least twenty (20) days in advance of the date that [TASL] estimates construction of the Premises will be substantially completed in order for [ECO] to plan and coordinate [its] move-in and occupancy of the premises.... ” This provision was intended to give ECO time to install telephone lines, computer cabling, and other utilities needed to operate its labs and offices before furnishing the space.
The lease gave TASL the responsibility to determine when the building was “substantially completed,” obtain certificates of occupancy, and notify ECO of those developments. It declares: “[TASL] shall notify [ECO], in writing, upon substantial completion of such improvements.... ” On September 28, 2001, ECO accepted the building as “substantially completed,” and the lease term began on October 1, 2001.
The notice of substantial completion from TASL, in turn, triggered ECO’s contractual duty to “submit to [TASL] a written punch list of items needing completion or correction.” ECO submitted an eight-page punch list to TASL on September 28, 2001. ECO’s actions gave effect to the following provision:
Subject to the Lessor’s completion of such punch list items, the taking of possession by [ECO] shall be deemed to conclusively establish that the buildings and other improvements had been completed in accordance with the Plans, that the Premises are in good and satisfactory condition as of when possession was taken, and that Lessee has accepted such buildings and other improvements.
Among other tasks for completion, the punch list submitted by ECO noted the need for caulking between the tilt wall panels under grade. Without that caulking, water would flow underground between the tilt wall panels and under the foundation.
*304 After timely receiving the punch list from ECO, TASL was to “use reasonable efforts to complete such items within thirty (30) days after the receipt of such notice .... ” On October 24, 2001, TASL transferred the property and assigned its interest in the lease to Ashford.
Deed of trust assignment
Also in October, Ashford sent a letter to ECO Resources entitled “Notice of Lease Assignment and Estoppel Certificate,” which explained that it intended to assign its interest in the lease by a deed of trust to the Lincoln National Life Insurance Company. Ashford further declared that the “assignment shall not impair or diminish any of [Ashford’s] obligations to [ECO] under the Lease....” Following Ashford’s agent’s signature comes a series of certifications, signed by both ECO and Ashford’s guarantor, Southwest Water Company, including certifications that:
• Tenant is in possession and in full occupancy of the Premises ... as of September 28, 2001.... Tenant has accepted the Premises without exception, except for undisclosed defects, and all requirements for the commencement and validity of the Lease, including construction work, if any, required of the Landlord under the terms of the Lease have been satisfied.
• The Lease contains all of the understandings and agreements between Tenant and/or Guarantor and Landlord, and is in existence in full force and effect, without modification, addition, extension, or renewal except as set forth above.
• There are no defaults or breaches under the Lease.
As of October 24, 2001, the date of the lease assignment, TASL had not performed the task of caulking between the tilt wall panels below grade, and Ashford did not undertake it either. When ECO later observed cracking floors, uneven and tilted floors, cracked walls, and other conditions related to foundation problems, Ashford retained structural engineers to investigate. In late 2003, those engineers discovered that large amounts of water had migrated and become trapped under the building’s foundation, which caused heaving and differential movement of the foundation and exterior and interior walls. Ashford’s expert determined that the influx of water resulted from the failure to caulk the tilt wall panels below grade, the same task ECO specified was left to be done on the punch list.
Discussion
I. Breach of contract
Ashford challenges the determination that Ashford breached the lease by contending that (1) ECO lacked standing to pursue its breach of contract claim against Ashford; (2) no enforceable contract existed at the time of the breach as a matter of law; and (3) the evidence is legally insufficient to support a finding that Ashford breached the lease.
As for Ashford’s standing challenge, we acknowledge that the question of whether a party is entitled to sue on a contract is sometimes informally referred to as an issue of standing. Nevertheless, because the issue does not affect the court’s jurisdiction, it is not truly one of standing, but one on the merits of the contract claim itself.
See Yasuda Fire & Marine Ins. Co. of Am. v. Criaco,
II. Standard of review
In reviewing Ashford’s challenge to the verdict in favor of ECO, we may set aside that verdict as based on legally insufficient evidence only if the evidence at trial would not enable reasonable and fair-minded people to reach the verdict under review.
See City of Keller,
We also review the trial court’s denial of a motion for jnov under a legal sufficiency standard.
See City of Keller v. Wilson,
III. Contract interpretation
We construe a lease under the well-established rules of contract construction.
See Luccia v. Ross,
The basis for the breach here was the failure to “cause the building to be constructed in accordance with the Plans.” As Ashford observes, a breach of contract action accrues at the time of the breach.
See Stine v. Stewart,
We agree with the trial court. The construction Ashford advances would be correct under the facts only if the lessor’s construction oversight duties ended when construction was “substantially completed” and did not include the duty— arising after substantial completion — to “use reasonable efforts” to complete the construction or repair of the items that ECO identified on the punch list within thirty days of its submission. “We cannot adopt a construction that renders any portion of a [contract] meaningless, useless, or inexplicable.”

IV. Ashford’s affirmative defenses
Ashford next contends that ECO waived its breach of lease claim, or, alternatively, is estopped from pursuing it.
A. Preservation of error
Before examining Ashford’s waiver and estoppel contentions on their merits, we first consider ECO’s claim that Ashford failed to preserve error on its affirmative defenses. To preserve a complaint for appellate review, a party must first present the issue to the trial court. Tex.R.App. P. 33.1(a). The party must show that (1) the complaint was made to the trial court by a timely request, objection, or motion and (2) the trial court ruled on or refused to rule on the request, objection, or motion.
Id.
Accordingly, we address Ash-ford’s legal-sufficiency complaints concerning its affirmative defenses only if it first raised those complaints in (1) moving for a directed verdict; (2) objecting to the submission of the jury question on breach of contract or tendering substantially correct jury questions or instructions on its affirmative defenses; (3) moving for judgment
*307
notwithstanding the verdict; (4) moving to disregard the jury’s answer to a vital fact issue; or (5) moving for new trial.
See Cecil v. Smith,
In its motion to disregard jury findings, or alternatively, for jnov, Ashford contended that ECO waived its breach claim by taking possession of the premises under the lease, pointing to the portion of section 1(A) that declares “the taking of possession by Lessee shall be deemed to conclusively establish that the buildings and other improvements have been completed in accordance with the Plans.... ” Ashford also raised the estoppel ground, pointing to ECO’s acknowledgment that “all requirements for the commencement and validity of the Lease, including all construction work, if any, required of the Landlord under the terms of the Lease have been satisfied.” We hold that, to the extent Ashford’s waiver and estoppel complaints conform to the jnov grounds it urged in the trial court, Ashford’s motion sufficiently preserved them for appeal. 3
B. Proof of waiver and estoppel
The Texas Supreme Court concisely set forth the definitions and elements of both waiver and estoppel in
Ulico Casualty Co. v. Allied Pilots Association,
the doctrines of waiver and estoppel are frequently referenced together, but they are different. Waiver is the intentional relinquishment of a right actually known, or intentional conduct inconsistent with claiming that right. The elements of waiver include (1) an existing right, benefit, or advantage held by a party; (2) the party’s actual knowledge of its existence; and (3) the party’s actual intent to relinquish the right, or intentional conduct inconsistent with the right. Estoppel, on the other hand, generally prevents one party from misleading another to the other’s detriment or to the misleading party’s own benefit.
Id.
at 778 (citations omitted). “The doctrine of equitable estoppel requires: (1) a false representation or concealment of material facts; (2) made with knowledge, actual or constructive, of those facts; (3) with the intention that it should be acted on; (4) to a party without knowledge or means of obtaining knowledge of the facts; (5) who detrimentally relies on the representations.”
Ulico Cas. Co.,
We first address Ashford’s argument that ECO waived its breach claim by taking possession of the premises under the lease. In relying on section 1(A) of the lease, Ashford omits to mention the very language that precludes any finding of waiver based on that term. The complete sentence Ashford relies on reads: “Subject to the Lessor’s completion of such punch list items, the taking of possession by [ECO] shall be deemed to conclusively establish that the buildings and other improvements had been completed in accordance with the Plans.” (emphasis added).
*308 The taking of possession, therefore, deemed completion in accordance with the Plans except for items specified on the punch list. The jury findings stand exclusively on Ashford’s failure to cause completion of a punch list item. The plain language of the lease renders Ashford’s position untenable.
Ashford’s position on the estoppel certificate language it selectively quotes is equally unmeritorious. Under that provision, ECO certified: “all requirements for the commencement and validity of the Lease, including construction work, if any, required of the Landlord under the terms of the Lease have been satisfied.” Under a reasonable interpretation of the lease, “construction work ... required of the Landlord under the terms of the Lease” includes the punch list items. Consequently, we hold that the trial court correctly denied Ashford’s motion for jnov. Further, because the tidal court properly rendered judgment in favor of ECO on its breach of contract claim, the trial court correctly awarded ECO its attorney’s fees.
V. Measure of damages
Ashford next contends that the trial court submitted an incorrect measure of damages to the jury. The trial court charged the jury:
What sum of money, if any, if paid now in cash would fairly and reasonably compensate ECO Resources for the damages, if any, that resulted from Ash-ford’s failure to comply with the Lease? Consider the following elements of damages, if any, and none other:
The difference, if any, between the rent required under the Lease and the rental value of the Leased Space in its actual condition.
Ashford asserts that the trial court should have submitted ECO’s damages claim under the measure applicable to defective construction claims-“the reasonable cost of remedying the defects when, as here, they can be remedied without impairing the building as a whole.”
We disagree. “In a suit for damages on account of the breach of an agreement for the rental of real estate the usual measure of the damages recoverable is the difference between the agreed rental and the reasonable cash market value of the leasehold.”
Rainwater v. McGrew,
Conclusion
We hold that the trial court correctly entered judgment on the jury finding that Ashford failed to comply with the lease because the evidence and the language of the lease support that finding, and Ashford failed to show that it was entitled to its waiver or estoppel affirmative defense as a matter of law. For the same reasons, the trial court correctly awarded ECO its attorney’s fees on its' breach of contract claim. We further hold that the evidence and the law support the measure of damages submitted to the jury. We therefore affirm the judgment of the trial court.
Notes
. Ashford also contends ECO cannot recover from Ashford because ECO lacked privity of estate with Ashford. We do not address this issue because neither ECO's live pleadings nor the trial court’s judgment refer to a claim or ground of recovery under that theory.
.
See, e.g., Tennessee Gas Pipeline Co. v. Technip USA Corp.,
No. 01-06-00535-CV,
. ECO also suggests that the language in Ash-ford’s pleadings limits the assertion of its waiver and estoppel defenses, but ECO waived any complaint about the limitations of that language when it responded in full to Ashford's waiver and estoppel complaints in its motion to disregard jury findings and for jnov.
