Hi ! I'm having trouble displaying/hiding some subquestions with conditions. Here's the layout :
[Q1] How do you communicate with medical services? 

• [Q1_a] Phone call
• [Q1_b] Online form
• [Q1_c] Face-to-face
• [Q1_d] Email
• [Q1_e] Letter

[Q2] You selected several communication modes [Q1_a] & [Q1_d]. How much do you like communicating through each of them? Please use the sliders, with 0 = I don't like to communicate like this at all and 100 = I love communicating like this.

I designed Q1 as a multiple answer question type, and Q2 as Multiple numerical input Question type, with sliders from 1 to 100 in Q2. The subquestions in Q1 and Q2 are the same, but I want only the subquestions selected in Q1 to appear in Q2. So in this example, only the sliders for Q1_a and Q1_c should appear. I'm having trouble finding where I can do so, I can only set conditions for questions, and not for subquestions. 
Thanks a lot for your help !

Hi,
of course you can set conditions on subquestions
 

But in your case the buzzword is "array filter".

Set the array dilter of Q2 on Q1. Remenber: Identical codes".
Read the manual about question types.

For these cases, it is always good to provide a little sample as LSS (not LSQ or LSG) so that we can have a look at your setup and play around with it and don't have to setup our own little survey replicating your case. Less work for us, quicker responses.

Usually you can set subquestion relevance, but you can also use the array filter.

[edit] Joffm, beat me to it...

Huge thank you holch and Joffm for your help. I tried the Array filter and... it worked just fine ! I'll make sure to add the LSS file if I have another question.
