True... I had thought about this, but it does add some complexity because of security issues. I'd have to think about a login/password scenario etc. I realise that there is probably stuff out there to handle that already, but as I'm relatively new to CGI, my way seemed like a safer and possibly simpler path. Plus the editing of the spreadsheet can be done off-line (we have dial-up :( )
Thanks, it is all food for thought.
