Ok <g, after a breath of fresh air, revisiting your original post ..
.. to multiply three colums together then add them together ..
Do this first:
.. to multiply three colums together
Assume data in cols A to C, from row1 down
Then place in say, D1: =A1*B1*C1
Copy D1 down
Then we could just place in say, E1: =SUM(D:D)
E1 should return the results you want
(Trying to keep things simple here since you are a newuser)
