Hi Jo

Anything change when you press F8 ? If so then calculation is turned off.
Reset it in the Tools Options menu.

HTH. Best wishes Harald

Sorry. Yeh I know you need more detail.

I have about 140 numbers in a colum from D5 to D145. At the bottom there
is
a total, adding the cells in the colum together. When I change lets say
cell
D50's number in it, the total at the end must also change reflecting the
number that was changed in this cell. Now when I change any cell in the
colum's value, the total stays the same.
