My husband, just called me from work because I'm supposed to be a big Excel guru, or at least all the engineers who work with him think so, but this one has me floored!

He was in the middle of a spreadsheet he uses everyday and entered a number. 0 showed up, so he looked at the value, and the number had been divided by 100,000,000,000! After that, each number he entered did the same thing. It's even happening in other spreadsheets.

Any ideas?
