I have some columns and i need pr line to add say from O:S and then multiply with corresponding values from column N
So first sum from O:S then multiply with N:N
I could do =SUMPRODUKT(N:N;O:O) + SUMPRODUKT(N:N;P:P) + SUMPRODUKT(N:N;Q:Q) + SUMPRODUKT(N:N;R:R) + SUMPRODUKT(N:N;S:S)
so I multiply N with each of the columns O to S but im sure there is a better way !
Specialy since it could be from S through QQ and that would be one boring formula to write
