I'm with Adam. It took me about an hour, and half of that was trying to cram 3 "if" statements into one formula. (I gave up and put them in three.)

A little more time and knowhow,and I'd have a fully-functioning one, complete with interface to make things automatic (which I currently don't know how to do, hence the "more knowhow"). Right now, you'd need a lot of sheets.

If anyone wants it, email me.
