Formula Error Message in Excel 2007 Sheet

[Cyberdude]

I'm trying to convert an Excel 2003 workbook to an Excel 2007 workbook, and I keep getting the following error message:
"A formula in this worksheet contains one or more invalid references.
Verify that your formulas contain a valid path, workbook, range name, and cell references"

There is no indication where these invalid references might be, and this worksheet has LOTS of formulas. I clicked the error detection button, but it doesn't do anything. Does anyone have a technique for finding the invalid formulas?

Hmmmm...... Can you have this line without Excel asking for your password, and if so, have you left the workbook now with not protection?

IT worked for me. I understand that in 2007, there is an issue with it.

Yes, the Workbook is unprotected. Thhose Subs are utilities I wrote to help me troubleshoot other peoples workbooks.

My own Workbooks never have problems

Hey, nice work, Sam! I'll get to work on it tomorrow morning. This is the weirdist proplem I've had today, except for trying to assign a macro to a shape (rectangle). I still haven't licked that one. All my old shapes accept assignment OK. (Pffft!)
