Weird Excel problem

[puggit]

My boss has sent out a spreadsheet which has a strange feature.

If I go to cell A1 and input '1' and cell A2 and input '2', then go to cell A3 and input '=A1+A2' it correctly give the cell a value of '3'. If the figures in A1 and A2 are then changed, the value in A3 does not change!?

Any ideas?

sounds like calculating is set to manual, instead of automatic.

Tools > Options > check the radio button next to Automatic calculation
