Probably nothing.

See here for the probable cause:

Ignore the fact that the page says Excel 97, as you aill also see in the
small print it actually applies to all versions of Excel.

If you simply format to acctg or some numerical format and a few decimal
places of precision, it will appear as 0.

I have a simple calculation C8-C14 that I use to figure my budget
difference. It works in all the monthly columns I have set up except for
one. I get a result of

-1.42109E-13

What could I have done wrong?????
