"We" (meaning you of course), are sooooooooooo close. That does work, sort of. The second half of the problem (and I didn't think there would be a second half but there is), is that there are two related listboxes, with transfer enabled between them. Your formatting works perfectly on the "first" listbox, but not on the "second" one, for reasons way over my head. If/when you are inclined to give me more of your time, any suggestions on the second box? Anything I've tried either blanks out the field or leaves it unchanged, in which case it becomes blanked out when I transfer back to the source. I suppose I could live without being able to transfer back if that becomes a big issue but I'm completely confused now...
