I would like to allow a user to select data with 3 options. I've used
checkboxes when the option is just on or off (incomplete or
complete). Sometimes the data does not apply, so I'd like a
"checkbox" which allows 3 conditions: N/A, on (complete), and off
(pending/incomplete).

I'm already using VBA macros to implement changes based on the
checkboxes. It would be nice to tie code options based on a 3 (or
more) position switch control. Is there such a thing?
