Kim,

You have to both Requery( "TheView" ) to cause the view to update according to the new parameter value and the Combo2.Requery() to cause the cbo to reread it's RowSource and update it's internal list of values to display.

>I called combo2.requery from combo1's InteractiveChange method.
>But the combo2's list does not change at all.
