Click Tools/Options on Excel's menu bar; click the Calculation tab on the
dialog box that appears and click on the Automatic option button.

I am having trouble in a simple task - copying a formula from one cell to
another.

Example:
Cell A1 has value 4, Cell B1 has value 5, I set C1 = A1+B1 and excel calcs
as 9.
Cell A2 has value 1, Cell B2 has value 2.
I copy the formula from C1 into C2 and excel shows the formula shows as
A2+B2. When I hit enter, C2 shows the value of 9, although the formula
shows
A2+B2.
To correct this error, I have to go into C2 and when the cells A2 and B2
are
highlighted and hit enter, Excel recalculates to the correct value of 3
(1+2).

Does anyone know why this happens?
