1. The second line below is redundant.
lstEmployer2.Clear
lstEmployer2.Value = ""

2. The following is not a work-around. That is actually a good best-practice in error trapping.
I figured out a work-around by disabling the 2nd listbox if it has a single item in the list. That way, the macro won't check that listbox at all.
If there is ONE item, then there is NO CHOICE, and therefore that value is (assumably) correct. In which case.....why check it?
