I am trying to make an excel program such that clicking a check box will
bring in 5 year budget data from another worksheet into five separate cells,
and the data will flow into =SUM equations. Also important is that when I
uncheck the box, the data disappears. I will need to make about 40 of these
check boxes, each of which refers to a different line of data. The options
the user will check off are not mutually exclusive, so I need any number of
them to appear or disappear simultaneously.

I would appreciate any guidance on what I imagine is not a difficult
problem, but too difficult for me.
Thanks!
