How do I tell when no selection has been made when a user has clicked OK on
my UserForm that contains text and list boxes? I get the text box input and
the listbox selections fine, but none of the following tests identify when
the user fails to select anything in the list box.
If IsEmpty(InAIOwner) Then MsgBox "..."
If Len(InAIOwner) = 0Then MsgBox "..."
If InAIOwner = "" Then MsgBox "..."
How do I test for no selection?

I appreciate your help, -John
