On my form I have a combo box that is the criteria for a second combo box. Each time I change the first combo box, my new results show up in the second combo box when I hit the drop down arrow. But still showing is the first go arounds selected result until I choose another result. How do I clear the second combo box each time I select within the first combo box. Thanks very much. Jim

OnEnter the first combobox, set the 2nd to null, OnExit the first combobox requery the second combobox.
