Unfortunatly my old brain is not what it used to be. My problem is that I
need to make up a simple formular that will allow me to enter different
amounts in a cell multiple times and get the answer as follows. I need a
figure that After deducting 10% to one cell and 20% in another cell the
answer will come back with what I put in the first cell. In other word a
reverse formular.

If you want the answer in cell A4 to be the same as what you put in the
first cell, say A1, then just put the following formula in A4:

=A1

If that's not what your looking for, please explain in more detail with
an example of the actual numbers you are using and the actual number you
are looking for.
