Wonderful. This actually seems to work with a couple of sample datasets that I had laying around. I'll try it with real data from the application on Monday (I'm home now and all of that stuff's at work). A few minor modifications and I can put it in production code.

I don't see anything wrong with it. (And I see one of my mistakes, *DOH*. I hate mental blocks.) I'll let you know how it works on Monday. Thanks!

PS: does anyone have a need for an ad-hoc report writer? Outputs in Excel, PDF, text, HTML given some XML input and massaging... :)
