Jonmo: Yes, thanks, that's much simpler. I use that for smaller spreadsheets, but find that when others have to use a spreadsheet with 40+ tabs, an index page is helpful where I've grouped the tab names by subject, put boxes around them etc. When I hit 150 tabs, I find that even if I created the spreadsheet, it gets a bit daunting when you back a year later and try to recall tab names. Nevertheless, your suggested approach is definitely better for most spreadsheets. Thanks.
