Both of them merely have a grid and a few methods. For all intents and purposes, I cannot see any difference between them and other simple forms I've created.

Add code in the Error event of both of the forms and use

Aerror(errorArray)

to trap errors! Also make sure to turn debug option on for the project before you build it.
