Tobias, Thanks. I never thought of the ListBox icon being in the View tab set of icons.
When I included the 3 required ListBoxes, deleted the 3 ComboBoxes & changed the coding from ComboBox to List box, it all worked OK. A mystery why the ComboBox coding didn't work! The required item did not always get selected when I selected another item in a different ComboBox. And there are no timers.
