Formula vs Automatic calculations

LyndaRousseau

I have built a formula to calculate the sum of all the datas in a column matching some criterias in one sheet. The thing is, and I don't know why, I end up being short of 3 compare to the automatic calculations of that column when applying filters corresponding to my formula's criterias. I'm going CooCoo here !!

Please Help !!

Tx !

Are you able to provide some screenshots for context? What is the exact formula you are using, and what are the filters you are applying?
