I spent 15 minutes last night carefully documenting both the back-end code and my output, the stupid form must have erased my post because it's buggy on my older Mac (or because it contained code, I'm not sure). I'm posting on my PC now just to make absolutely sure my code doesn't get dumped again. I also note, by the way, that the text box width is far wider than the allowed display area, so it scrolls to the right while I type rather than allowing me to see the whole thing.
