I want to format a cell to keep a total. We will call this cell T. I want it
to keep a total from cell A which when I put a number it will add to the
total in cell T. I also want cell T to keep a total from cell S so when I put
a number in S then it will subtract from the total. Ok I know how to do that.
My question is when I put a number in either cell S or A I want to be able to
see that entry but then if I want to add another number to it the total adds
that number also.
Here is an example T=0, I put 20 in A. Now T shows 20 and A also shows 20.
Now I want to put 20 in A again. I want for T to show 40 now and A to show
20. When I do this it does not change the total.
