excel urgent help

[Camalot]

My supervisor needs to change a cell that holds the budget hours but it keeps saying its locked, when she clicks unlock spreadsheet it asks for a paasword. Neither of us have the old managers number, is there any other way to change the cell?

Cheers.

I'm home now, thanks for the replies.

I've found my old managers number out, so I've text it to my supervisor so she can phone him.

If hes changed numbe, or doesn't remember it. I read you can open the spreadsheet in Open Office, then re-save it again to remove the password?

Thanks again guys.
