I have a row of data (only six items).

A B C D E F
1 3 9 4 2 8

A table of two columns
J K
1 3
2 2
3 1
=4 0

I want to look up each of the values in A to F, assign a value from column
K and Sum the results at G2

So values would be 3,1,0,0,2,0 and the Sum in G2 = 6

I have tried SUM(LOOKUP(A2:F2,J2:J4)) but end up with a #VALUE!

Any help appreciated.

Thanks,
Mal
