I have a spreadsheet that has simple sum formulas and conditional formatting
in the cells with the sum formulas. My formulas have stopped calculating and
any new formulas that I enter do not calculate. Any idea what might be
causing this? Thanks for your help!

Is you calculation on manual?

Tools Options Calculation Make sure it's set to automatic.

ToolsOptionsCalculation can be Auto or Manual.

Excel takes the Calculation mode each session from the settings on the first
workbook opened in that session.

i.e. If you saved Book1 with calc mode in manual and opened it first, calc
mode would be in Manual.

If you saved Book2 with calc mode in auto and opened it after Book1, Book2
would be in manual mode(Excel ignores the auto calc mode in this case).

If you close Book1 before opening Book2, Book2 will be in auto calc mode.

Confusing enough? <g
