Hi
Maybe Excel is set to Manual Calculation. Have a look at
Tools/Options/Calculation tab and make sure it's set to Automatic

Spreadsheet set up for capacity planning. However when I change the
number
of staff, the formula's behind the cells are not immediately updating the
results. Results are only updated after I have saved the spreadsheet.
What
could be the cause of this?
