Hello,

I am using Excel 2007 Beta (12.0.4407.1004) MSO (12.0.4407.1005) and
having a calculation error that is not present when I open the same
file in Excel 2003. I am getting the NUM error in sum and subtotal
formulas that will move from cell to cell as I recalculate the sheet.
This happens even when none of the cells referenced in the formula have
errors or other problems themselves. I can open the same file in Excel
2003 and not be able to reproduce the error. This file relies on the
use of circular references and the iterations settings are identical in
my installs of both 2007 and 2003.

Any thoughts or suggestions?

I like some of the new features, but if this problem persists through
the retail version, I will request that my IT department not upgrade my
group's machines.

Terry
