Basic Question: automatically updating cells

[mandyd]

Hello everyone,

I have a problem with my excel spreadsheet.
I have simple calculations such as cell3 = cell1+cell2, or using SUM() etc.

But when I update cell1, cell3 is not automtically updated. I have to go to cell3 and click in it, to get it updated.

In the past when I've used excel it just automatically updates cell3 if I made changed to cell1 or cell2, what is wrong?

Go in Excel options -> Formulas and in Workbook calculation check is it Automatic
