Cells not calculating

What do you mean by "a document"?  Exactly what type of file is it?  (Note: a CSV file is __not__ an "Excel" file.)

What do you mean by "not calculating"?  Exactly what do you see in the cells (not the Formula Bar)?  For example, the formulas themselves?  Previous non-zero values?  Zeros?  Excel errors like #VALUE?

The __format__ of a cell does not matter.  The __type__ of cell value does.  Looks can be deceiving.  Use formulas like =ISNUMBER(A1) to determine if the cell value is indeed numeric.

If this and other suggestions do not point you to the problem, attach an Excel file (not an image or CSV file) that demonstrates the problem.
