Thanks for your answer Bob,
I am going to try this formula right away .
One thing, I don't understand why you used the "--" in the formula.
Could you tell me please ,
Thanks

Ray,

I am not quite sure what you were doing, but is this what you want


=SUMPRODUCT(--(E4:E2337=2);--(E4:E2337<=5);--(D4:D2337="yes"))

Hello

I try to to use 3 critéria in a formula with the Countif function.
Actually
two of them represent a bracket.
For the calcul of the bracket I found the good result by using :
=countif(E4:E2337;"<=2")-countif(E4:E2337;"<=5")
where I am in trouble is when I try to add the third criterion in my
formula
=countif(D4:D2337;"yes")
I tried those math operators but none of them works +, -, *

Do you have an idea ?
Thanks
Ray
