Formulas not Calculating

[pgerardi]

Looking for some help. I have a simple worksheet that sometimes will not calculate (=sum). If I do a page down & then page up it will do the calculation but not automatically. Before anyone says to go to calculation options & make sure that it is set to Automatic, it is. This is making me a little uneasy.

Thanks

Thanks, wondering if it is a Microsoft issue.
