Check All Boxes
 

I have a worksheet set up that has 6 different divisions and then the
Sub-banners associated with those divisions. I currently have it set up
where each Sub-Banner has a check box and if you click the check box that
Sub-Banner is added to a different worksheet for setting up new items. I'd
like to add an ALL check box at the top of each division that if you check
that box, it put check marks in all the Sub-Banner boxes in that division
instead of having to check each one individually.
