Mysterious Excel Problem! Cells changing from formulas to values!

[jd19963]

Random cells are changing from formulas to unformatted values with no apparent reason!! These cells need to by formulas not values!!

Does anyone have any explanation for this and a way to solve it?

It's hard to know without looking at the workbook, maybe maybe attach a zipped copy of the workbook....

Have you got any macros, if so disable them and see if the problem persists.
