Please, could any one help me to save the result resent in a cell following a
calculation (by functions), despite changing the parameters affecting the
results?

For example;

If I do a*b=c

I want the result €œc€� to be saved in a cell while I change €œb€� to €œd€� in the
same function.

If now a*d=e

I would like a row, somewhat like the below

€œc€�
€œe€�
..
..
..

Hope this is clear.

Thank you
