To start with, check that Tools/ Options/ Calculation is set to automatic,
not Manual.

Beyond that, you'll need to give us more information. What formula are you
using? What numbers are in the cells feeding into that formula? What
result did you get? What result did you expect?

Hi,

I am accountant, I finished one excel worksheet and saved it and closed
it.
The next day I reopened it and I found most of the figures changed, some
changed to '0'. What's the reason? Because I pressed F9 the other day and
it
caused some change? How can i change it back? Please help, thank you so
much.
