Hi,

I hope someone can help me with the following problem.

..... A B C D
100 .. 1 2 N1
101 3 4 5 N2
102 6 7 8 N3
103 9

I want to do this:

1 * 2 * 3 = N1; then:
4 * 5 * 6 + 1 * 5 * 6 = N2; then:
7 * 8 * 9 + 4 * 8 * 9 + 1 * 8 * 9 = N3; etc.

Does this require some kind of macro and if so, where might I find an example?

Thanks in advance.

Bill
