How to sum values in a table row that match a given index
Is there a way to set up a formula in numbers that will sum up values in table columns that have a certain index number in another column.
for example:
A B C
1 5 10
3 4 12
5 5 15
3 2 12
I would like the sum of the values in column B & C where there is a 3 in column A.
In this example the formula would return 30
