How do I divorce a pair of toggle buttons from the source I copied them from?
I made a yes toggle, copied it to make a no. I set them = to G3. The
originals are called "option button 1" and "option button 2". When I copy
them, I rename the new 2 buttons, "option button 3" and "option button 4" and
set them = to another cell (G4). But when I click any of the 4 buttons I
just created, it deselects all but the last one.

How do I make it so the selection toggles between just one pair?
