I’m having trouble finding a simple way to count “X”s marked in a row, but in specific columns.

On the left (highlighted in pink), I have various categories of “rope replacement reasons”, and on the right, there are columns to log each instance of rope replacements with “X” marking different reasons.

I want to add all instances of “core” marked with X on anchor #1, all “fuzz” marked with X on anchor #1, etc.

i’m not sure how to do this..
