Hello,

I would like to have a filter from a multiple choice question to a single choice (list radio).

For example i have a multiple question as below

Q1- which are your brand?

• brand 1
• brand 2
• brand 3
• brand 4
• brand 5
• brand 6

 If i select Brand 5 and brand 3,  i would like that in Q2 "which brand do you choose between them" (list radio) , it would appear only brand 5 and brand 3 as answers.

I tried with array filter but it doesn't work.
 

Hi,

but it doesn't work.

This is the worst desciption of an issue.

Did you really consider this?
 
I am rather sure that your codes are different in both questions.

Otherwise send a lss export of these two questions.

Did you use the correct question code in the array filter setting?

Are your sub-question and answer codes identical?

Sorry, i am a basic user of limesurvey
below the questions

Multiple question Q1 "which are your brand?"
code     
SQ002 brand 1
SQ003 brand 2
SQ004 brand 3
SQ005 brand 4
SQ006 brand 5

Single question list radio Q2 "Which brand do you choose between them?"
code 
A2     brand 1
A3     brand 2
A4     brand 3
A5     brand 4
A6     brand 5

I set array filter in the Q2 towards Q1. But if i select brand 3 and brand 5 in Q1, then the filter doesn't work in Q2. I would like that in Q2 will appear only the brands selected in multiple question
   

As we both assumed:
Your codes are not identical.

In Q1 you use "SQ001",...
In Q2 "A1", "A2",...

Thank you, now it works!

But i have a problem with "other". If i do the possibility of the option "other" in Q1 but the respondent doens't put any comment, it appear in Q2 even if there is no comment in Q1. I tried to put {Q1_other} in the answers option of Q2, but i have the following result 

Sorry,
if you do not show us what you did, which codes you used, it is difficult to help.

Always the best:
Create a small sample survey with only these questions and send as lss export.

Joffm

Ok thank you a lot for helping

Multiple question
 

Single question
 

This is the result, but i wouldn't the button for other in Q2 if there is no comment in Q1
 

 

Well, not surprising, if you do not do what you are told and what you read.
I already showed this paragraph of the manual
 

And you already know that the codes have to be identical.
An option I always advice is:
Activate the survey, and have a look at the answer table.
Here you see very clear how you access the variables.
 
You see your "normal" codes "A4", "A5" and furthermore you see that the code of the "other"-option is "other"

Meaning in your filtered question this answer option also has to get the code "other"
 



If you enter a not existion code ("A6") this is fine, if you want to have a cascading filter, but always want to show something line "No answer", "No more", ...

Joffm

Thank you a lot for explaination!
Now  it works perfectly, i get the issue!
 

Hi Joffm,

Following the example above, is it possible to make appear the Q2(single question), only if there are two answers in Q1? while if in the Q1 the respondents select just one answer, Q2 shouldn't appear

I have no idea how to put this condition

Thanks

Count the selected options in Q1.
Only display Q2 if the result is greater than 1.
