Hi,

I have tried to find the right formulah, but failed.

I have three column

Amount A   Amount B    Amount C
30
10            20
                                         34

and a fourth column where I have to fill in % that applies to all
values A-C in the row.

12%
45%

How to make a formula in a cell that summerise all amount A's * the
respective %

For example:

30 * 12% + 10 * 45% =

Also for two other cells for B and C
