Adding Checkboxes Updating Formula

Lets see if this works... instead of formulas the code does the listing, and kept jeffreybrown's great checkmark code, just expanded to use any columns defined in an array at the start

I also made it more dynamic, so you can go to any row and the code should be good. (listing and double-clicking will work up to last row of the column it belongs with). So if last row in Col A that has data is row 40 then B and C will also work for clicking up to row 40.
