Problem with recursive click event.

After a selection made from a combo box I want to check to see if certain conditions are met if not I want to reset the combo box to force the user to make the appropriate selection. Then problem is that when I reset the combo box it triggers the click event again and I get a repeat of the test and the message. Is there a way to turn off the event checking for the combo box while I reset it.

Private Sub cmboTest_Click()

If condition Then
msgrtn = MsgBox("Incorrect selection made", vbOKOnly)
cmboTest.ListIndex = -1
Exit Sub
End If

End sub
