Thanks, Mr. Deitrick, for solving my problem. It's about 80% there for my purposes. However, for how I described it, it's 100% solved. I'll have to think about how to re-explain the remaining 20%. Of all the spreadsheets I've built out, this particular one is most vexing. There's a proprietary app that sort of does it already, but it spits out a highly customized (Excel) report that I can't manipulate. It's nearly impossible to put in columnar format (it has headers and wacky spacing and indents). If I could do that, it would be problem solved. I'll probably re-post when I get my thoughts together. Thanks again.
