I have two columns of numerical data. I'm trying to sum the values of a column only when they are equal to the corresponding values in the adjacent column. For example, if I have two columns:
3 4
2 9
3 7
7 7
6 2
5 5
The sum would be 12.
I haven't been able to get this to work quite right using the SUMIF variants.
Any ideas will help. Thanks.
