Well, hey, I still say there should be some sort of 'required' attribute for controls, but this seems to work so I guess this is what I'll use. Thanks Bruce, Michael, and everyone else for their assistance!

Ok, it does work when I include the nodefault. But, if you have nodefault you can exclude the other setfocus. So, the code looks like this:

if empty(this.value)
=messagebox('Required field')
nodefault
endif



Thanks again!
