How do I create a second combo box, from a first one? I am trying to make a
hierarchical sheet listing, so the first box has file names, and the second
should show sheet names. I am passing the top, left, width and height, to
offset the position of the second box, and the name of the first so I can
name the second one, modifying the name to reflect that it is a 'sub' box.
For example, if the first is named,"Simpsons", I would like the second to be
named "SimpsonsSub". I do not want the second box present unless a choice is
made from the first box. Is this possible?
