Matt,
Thank you very much for tip, I did what you instructed and it worked. Now if only I can preview/run the form without the problems I'm inquiring.
I have downloaded the following from HOW-TO
1. Populating Fields After Selection
2. Populating Table Row after selection (Rules)
3. Populating Table Row after selection (Code)
4. Fully Editable Drop-Down List Box
Except for #4, the rest I can not preview/run the forms without running through the problem.
