Ok... I have a listbox that is based off of two combo boxes... Once you choose a selection in cbo1 it gives new choices in cbo2. Once you make a selection in cbo2 it populates lbo1. However, when I change cbo1 to a new selection the lbo1 doesn't blank out. It keeps the existing data until I make another change to cbo2. Any help to have the lbo1 blank out until I make the final choice?
