SUMIF formula if another cell has "YES"

Hello
=SUMIF(A:A,"YES",B:B)
but unlike your first message, the YES is now in A and the amount is in B
My friend Eric didn't have much chance of getting it right on the first try!
best regards

Thank you for this response Vaucluse!! THIS IS EXACTLY IT.

And if, for example, I want to take an initial balance (like +10) into account in my total of column B, I put this formula:

=SUMIF(F5:F11,"YES",10-G32:E11])?

Example:

Initial Balance: 10

Column A Column B
1: YES 2
2: NO 2
3: YES 2
4: NO 2


Total: 6

( Basically, I want to find the result of 10 - Row 1 and Row 3, noting "YES" in column A.)

I don't see what G2 has to do with this? Still not clear!
SUMIF requires that both fields have the same height and what you're proposing doesn't correspond to anything:
Moreover, you're talking about a total B with a formula that mentions R and G????
If we take your request literally and to stay within the formula of columns AZ and B:
If you have an opening balance in C1:

=SUMIF(A:A,"YES",B:B)+C1

Otherwise, try to be much clearer!!

Perfect Vaucluse, thank you for the help ^^
