IFCOUNT fonction

Hello,

I'm using Excel2016,

I'm freezing in a function formula and I need help from the community.

I'm trying to get a count of "X" of all range E8 to E15, the result will be in E6 if only "S" is written in D column the same row of X. (joined piece "Capture"

I can't add some new columns into the right of the XLSX document because I have to do a big review otherwise.

thanks in advance.

I'm looking forward to hearing from you

Pascal.
