This one is kinda complicated, I admit. Unfortunately, I didn’t really take the time to clean up the spreadsheet file for others to follow (I don’t really have the time these days). Sorry. But try to take it apart – and ask me questions if you have them.
I’ve canvassed some other folks from the Excel community to see if they would want to do a video tutorial of this – and I think that’s what it would take.
