James,
I understand the workaround now that you have explained about:
"trapping the Enter keycode before it is returned to the event, thus preventing the focus from moving to the next control."
It makes more sense now and explains why I(a novice)wasn't able to figure it out. Sure helps to be able to have your questions answered, thanks James and Richie for your help. The form is not all that important but the understanding is.
