Hi Gert, Yes, you did give me something to do - as if I'm not already busy enough? :-)
Your scheme sounds like an intriguing addition to the simplified spreadsheet, however, I have a looming deadline and need to finish the final draft of my book first before launching off on a complex spreadsheet design. Perhaps there are some in this group who can try developing this idea in the meantime? Thanks very much for your suggestion!
