My 2003 Excel just out of the blue stopped calculating the formulas. I've used this spreadsheet for 2 or 3 years now. What happened?:mad:

Could be corruption. Also, go to TOOLS > OPTIONS > CALCULATIONS and make sure the selection is still on AUTOMATIC and didn't somehow get set to one of the other options.

Thank you so much. It was the Tools Options, setting. Somehow over the weekend it changed to Manual instead of Automatic:)
