Box “You selected: Normal” Elseif opt. Heavy = True Then Msg. Box “You selected: Heavy Duty” Else Msg. Box “You selected: Pots and Pans” End If End Sub Slide 13

You can even place containers within containers. v The only way to move a control from other parts of the form into the frame is to cut and paste v Slide 15
