I have a listbox that is visible only when other criteria on the form is met. What I need now is a way to make it required to chose a line from the listbox when the listbox is visible. I'm drawing a blank on how to do this. Thanks.

In the method code where you make the listbox visible, add code to setfocus to it, ie.
Code: 
WITH ThisForm.MyListBox
   .Visible = .T.
   .SetFocus()
ENDWITH
Then, in the Valid of your listbox, have something like this.
Code: 
RETURN This.Selected
Regards,
Jim
