I created a spreadsheet using Office 2003 on an XP machine that on open looks
at todays date and checks it against a shelflife date using this code:

TodaysDate = Date

When a colleague using Excel 2000 on a Windows NT (or 2000, not 100% sure at
the moment) tries to open up the spreadsheet they get an error saying:

Compile Error:
Can't find project or library

and it highlights the word Date (the one after the equals sign). I thought
this was a standard VBA keyword, so I don't understand why this is causing a
problem. Can anyone shed some light for me??
