Hi Susan,

>I'm wondering whether anyone can tell me why my upper(thisform.mycombobox.value) isnt working? In other instances, for example, upper(thisform.mytextbox.value), it is working just fine. Did i do something wrong?

What do you mean "isn't working"? As in UPPER(COMBO.VALUE) returns lowercase characters? How many columns do you have? The Value may be in an undisplayed column. Does UPPER(COMBO.DISPLAYVALUE) work?
