I try to generate a list based on a criteria, but ...

Many thanks to the all the users who tried to assist me, especially to CARACALLA for his solution. We all have many things still to learn, me included!

Correct file.
The previous one had a wrong structure

G14=SUMPRODUCT((ISNUMBER(MATCH($A$3:$K$10,$F14,0)))*(N(+$B$3:$L$10))*(INDEX($A$3:$K$10,,MATCH($E$13,$A$2:$K$2,0))=$E$14))

Copy down


I14=SUMPRODUCT((ISNUMBER(MATCH($A$3:$K$10,$F14,0)))*(N(+$B$3:$L$10))*(INDEX($A$3:$K$10,,MATCH($E$13,$A$2:$K$2,0))=$E$14)*($A$1:$K$1=I$13))
