I see that you've marked the thread as resolved, but do you really want to disable the other CheckBoxes ? If the user can only select one correct answer then I would emulate the OptionButton methodology (as far as possible) and set all others to zero when one has been selected
Code:Private Sub Check1_Click(Index As Integer) Dim intI As Integer Static boChange As Boolean If boChange Then Exit Sub boChange = True For intI = 0 To Check1.ubound If intI <> Index Then Check1(intI).Value = 0 End If Next boChange = False End Sub
