I have a big problem. I am new for Qlik View and I don't know it well.
In the sample attached I don't know why if I select "K" for "CodDomanda2" and "2" for "CodRisposta" I have 3 values for "Indiv". If I see the input file Sezione2, I see That only "Indiv" equal 2 has the value 2 for field "K".
If you create a Table box for Sezione2 you will see you have lots more records than in the input script. If you look at the table viewer (CTRL-T) you will see you have a lot of '$Syn nn' fields, caused by badly joined tables. Try to change the field names to make sure you tables only join where they should.
