Hi, 
I was wondering how to filter subquestions to show based on a prior multiple choice question.
I attached the lss file :  
what i want to do is : 

1. If answer to subquestion 1 of the multiple choice question "eqNotoToCombi"  is choosen, show subquestion 1 of question "Q5Bis"  
2. If answer to subquestion 2 of the Y/N table question "Q4"  is choosen, show subquestion 2 of question "Q5Bis"  ... and so on for subquestions 3 to 16.

I started trying this way but it didn't work at all : 

 
 
Can you please help me with this ? thanks in advance.
 

Hi,
1.

multiple choice question "eqNotoToCombi"  is choosen

"eqNotoToCombi" is not a multiple question, it is an question of type "equation" that sets the multiple question "QNotoCombi"

2. The last line in this equation is wrong.
{QNotoToCombi_99=if(Q1_1=2 AND Q1_2=2 AND Q1_3=2 AND Q1_4=2 AND Q1_5=2 AND Q1_6=2 AND Q1_7=2 AND Q1_8=2 AND Q1_9=2 AND Q1_10=2 AND Q1_11=2 AND Q1_12=2 AND Q1_13=2 AND Q1_14=2 AND Q1_15=2 AND Q1_16=2 AND Q0Combi_99=="Y","Y","")}
Read the manual about single "=" and double "==" equal signs.

3. In this line you'd better use the function "countif".
Like
{QNotoCombi_99=if(countif("1",that.Q1)==0 AND Q0Combi_99=="Y","Y","")}
Read the manual about "implemeted functions"

4. There are no relevance equations in Q5Bis.

And please, ALWAYS mention the LimeSurvey version you are using.
