As a guess your claculation mode is set to manual. Iit is under Tools |
Options | Calculation...

Press <Shift + Ctrl + Alt + F9
for a full recalculation of all cells.

I'm putting formulas down an excel column but they don't work. Just by
chance I clicked on one of the referenced cells and pressed delete
(although there was nothing visible in it) and the formula then
worked.
e.g, I put formula in cell C2 which references cell B2 in
conjunction with other cells and nothing happens. I click B2 and press
delete and answer to formula now appears in cell C2.
Anyone know how I can deal with this? I have formulas to run down
nearly 300,000 rows and cannot do "press delete" for every occassion.
Thanks.
