Hi Arne.

The code to pop the list2 is in the InteractiveChange method of the list1 (tried click too but...). The first time through all works just fine. However, once an item has been selected in list1, I cannot select any other item in list1 (i.e. with the idea being to change the result in list 2) - just as if list1 had been disabled.

I a sorry but my crystal ball appears to be malfunctioning today < s >. Could you please post the code that you are using to populate the dependent list box as well as the code that you are using to set the RowSource for the controlling list box. It sound like your code is actually emptying the controlling listbox's RowSource when you requery the dependent list.
