You will need to give a little more detail, because you said you have 2 buttons, but then you described 3 buttons (Lookup1, Select, Lookup2). Did you just describe the 2nd button as both select and lookup, or are there 3 buttons? What EXACTLY is the form doing, what kind of controls are you using, does this include a repeating table of any sort, and what is the exact logic? If you can attach your XSN, I could troubleshoot it directly.
