I have a listview control on a form that in one project works as it should but in another doesn't. I get a "Run-time error '13' - Type Mismatch" error when I try to add a new item to a listview control.

Dim L As ListItem

Set L = lvwSelected.ListItems.Add(, , "Item 1")

The same exact control and the form the control is in works correctly in one project but not in another. Anyone know what's going on? TIA.
