Setting up Permissions or Security selection spreadsheet
 

I need to set up a Permissions or Security list and would like to use check
boxes.
The worksheet would have lets say 4 columns or 4 check boxes each pertaining
to a specific group. A B C & D
exp. If group A has permission the B C & D do.
If group C has persmission then D will but A & B will not.
I would like to check A and the rest will fall in but if I check C I only
want D to fall in and A & B will remain unchecked.
If you understand this at all please let me know your ideas or thoughts on
how this is achived.
