FILTER WITH DROPDOWN and GET A VALUE OF THE SAME RESULTING ROW...

Hi everyone, here is my question:

i have too different datasets, which are :
“questionDataSet” with columns: Question / Pourcentage
“ReponseQuestionDataSet” with colmuns : Question / Answer

(the questions that are put into “questionDataSet” are copied into “ReponseQuestionDataSet”)

into “ReponseQuestionDataSet” i’m searching for /Answer values/ matching my #dropdown1 values (connected to “questionDataSet”, “Question”).

$w(‘#ReponseQuestionDataSet’).setFilter (wixData.filter()
.eq(“question”, $w(“#dropdown1”).value)

and then i want to get the /Pourcentage value/ from “questionDataSet” on the same Row as the choosen #dropdown1 value.

Can someone help me ? I don’t know if i’m clear about it…

THANKS !!
