>>>I have a listbox on my form. The RowType is 5 (array). My problem is that based on certain criteria the RowSource can change. So, I change the RowSource and Requery but once I have changed the source the Listbox always remains blank. When I look at the RowSource while the form is running it does change the RowSource but the display doesn't work. What am I missing?
>>
>>I assume that new RowSource is also array. Is it possible that new array isn't visible to listbox because it's local? BTW, it'should work w/o requery().

>Correct, the other RowSource is also an array. Both arrays are properties of the form. I didn't think it would need a requery but don't understand why the listbox stays blank after changing the RowSource.

>For instance, when I load the form the listbox has 4 rows in it and these are visible. I click a button and this fires of the change of RowSource. The Listbox goes blank and refuses to show any values after this.

Stupid question: maybe new rowsource array is empty?
