I want some check boxes to be visible based on whether
another check box is selected. This is the code that I
have, I just am not sure where to put it. Thanks.

Private Sub Checkbox3_Select()
If Checkbox3.Value = False Then
Checkbox30.Visible = False
Checkbox31.Visible = False
Checkbox32.Visible = False
Checkbox33.Visible = False
Checkbox39.Visible = False
Checkbox40.Visible = False
Checkbox41.Visible = False
End If
End Sub
