Maybe you'd be better off with your own custom stand-alone application that generates Excel sheets. It would most likely be a little more expensive than $200, but it might be an easier solution than dealing with Excel.

Maybe... but I am not a programmer, and I have to support/update/enhance this application myself, so I'm pretty much stuck with doing it in Excel. Also, my co-author and I together have over 200 hours invested in this thing, and I'n not going to throw that away. Finally, the spreadsheet is working beautifully now, functional and bug-free. We just want to add that last, final (but not essential) feature to it.
