Need help to understand an expression( set analysis)

[OmarBenSalem]

Hi all ( @sunny_talwar ) (It's been a while btw, hope u're doing well !!)

Well my request is rather simple, to help understand this expression I made but that didn't do as I wanted it to :

Count( distinct {

<ID_QUESTION={'1'},Regroupement_ID={'2'},ID_REPONSE={'5','4','3'}>
*
<ID_QUESTION={'2'},Regroupement_ID={'2'},ID_REPONSE={'1','2','3','4','5','6'}>

} UserID)

What I want to do is :

Count the UserID that are part of Regroupement_ID=2 and responded to Question =1 by responses 3,4 OR 5

and to Question 2 by responses 1,2,3,4,5, OR 6

Isn't my expression supposed to return this?

Because it returns 0 while I'm pretty sure 0 is not the expected outcome.

What am I doing wrong?

Try this

Count(DISTINCT {<UserID = P({<ID_QUESTION = {'1'}, Regroupement_ID = {'2'}, ID_REPONSE = {'5','4','3'}>}) * P({<ID_QUESTION = {'2'}, Regroupement_ID = {'2'}, ID_REPONSE = {'1','2','3','4','5','6'}>})>} UserID)

Same result.. 0.

Don't understand why !

Create a straight table with UserID as dimension and two expressions

1)

Count(DISTINCT {<UserID = P({<ID_QUESTION = {'1'}, Regroupement_ID = {'2'}, ID_REPONSE = {'5','4','3'}>})>} UserID)

2)

Count(DISTINCT {<UserID = P({<ID_QUESTION = {'2'}, Regroupement_ID = {'2'}, ID_REPONSE = {'1','2','3','4','5','6'}>})>} UserID)

Do you see rows where both the expressions are giving 1?
