Excel Cells do not update.

[yamcha]

Hi.
I have a problem with a worksheet in Excel, I have an Operation with SUM, and i see the Result Ok, but when i try to use this Result in another Cell, this appear Ok the first time, when the Cell with the SUM changes, the other cell keep same, and i have to push <F9> to update the Cell.
I take the SUM result with &quot;=N128&quot; operation, to use in another Cell.

I want to the value update automatically.

I am working in the Same Sheet, and i have Win2000 Prof with Office 2000.

Any Idea ?
Thank You.

Check Tools, Options, Calculation Tab. Make sure &quot;automatic&quot; is selected.
