My formula doesn't update totals when I change numbers.

It is likely that the calculation mode is set to manual, not
automatic. Go to the Tools menu, choose Options, then the
Calculation tab. There, ensure that "Automatic" is checked.

I should have added that the calculation mode is determined by
the first workbook opened by Excel. So if you have a personal.xls
file, or any file, in your XLStart folder (typically C:\Program
Files\Microsoft Office\Office\XLStart), and that workbook has the
calculation mode set to manual, all workbooks will operate in
manual mode. Test to see what workbooks open (if any) when you
start Excel, and ensure that their calculation mode is set to
Automatic.
