When a trial court's order specifies the ground relied on for the summary judgment ruling, we only affirm the summary judgment if the theory relied on by the trial court is meritorious, otherwise we must remand the case. State Farm Fire Cas. Co. v. S.S., 858 S.W.2d 374, 380 (Tex. 1993); Macias v. Rylander, 995 S.W.2d 829, 833 (Tex.App.-Austin 1999, no writ); Farmer Enters., Inc. v. Gulf States Ins. Co., 940 S.W.2d 103, 106-07 (Tex.App.-Dallas 1996, no writ). Because the trial court's summary judgment order specifically stated that it granted summary judgment on Lykes, we need not address whether the "no evidence" standard for summary judgment applies.
