I've been reading the threads and I haven't been able to find answers to my Access 2007 problem. Im a decent user, Tables, queries, and basic forms with commands using the wizard - but Im stumped. I need to limit the values on Combo Box #2 based on what I selected in Combo Box #1. I'm pretty sure I need to use some type of VBA coding but I can't figure it out and can't find any decent tutorials online. Specifically, once I select "GS level 12" on my form, I want the user to only be able to choose "GS level 12" performance criteria in the next combo box. Any Help would be appreciated!
