I am using Excel 2003 and have my calculations set to automatic, but I notice
that there are times when my formulas do not calculate. If I click into the
offending cell and hit "enter," esentially re-submitting the formula, it
calculates. Since I am dealing with a large workbook with may worksheets
worth of interdependent formulas, I am worried that my data will be
inaccurate. Is there a limit to how many calculations an excel workbook can
do and have I reached it? Is there a way I can force a cell to calculate
even though there is nothing wrong with the formula, possibly with some vba
code or something? I appreciate any help since my credibilty at work depends
on presenting accurate data, and I have a real lack of confidence in what
excel is giving me.

Thanks,
L.B.
