Just upgraded to Office 2007, trying to do a very basic spreadsheet and
keep
getting the above error message, and I cant see why ?
I have a column, with values in A6:A9, I want to add these together and
then
subtract the total from a value in A10.
I'm using =Sum(A10-(A6:A9)), but keep getting the above error ? All cells
are formatted as General Numbers to 2 decimal places.
Can anyone help please ?
