Assuming both questions are single-choice radios, remove the script from Q1 and add something like this to Q2:

Code:
<script type="text/javascript" charset="utf-8">
  $(document).ready(function(){
 
    // The Q2 options corresponding to the Q1 options    
    teacherLists = {
      C1 : 'T1,T3,T5',
      C2 : 'T1,T2,T3,T4',
      C3 : 'T2,T3,T4,T5',
      C4 : 'T1,T4,T6'
    };
 
    // Identify this question
    var thisQuestion = $('#question{QID}')
 
    // The checked option in Q1
    var q1Ans = '{Q1}';
 
    // Hide all of the teachers
    $('li[id^="javatbd"]', thisQuestion).hide();
 
    // Now show the appropriate ones
    $(teacherLists[q1Ans].split(',')).each(function(i){
      $('input.radio[id$="'+{QID}+this+'"]').closest('li').show();
    });
 
    // Uncheck all hidden radios (in case page has been seen before)
    $('li[id^="javatbd"]:hidden input.radio', thisQuestion).prop('checked', false);
  });
</script>

Hey Denis, thank you for the suggestion. unfortunately, I'm a bit confused due to my lack of speaking French :/
Tonys version should work. If not, I'll come again and try the translator or just ask ;)
Many thanks to you!

This will work in 2.5x:

Code:
<script type="text/javascript" charset="utf-8">
  $(document).ready(function(){
 
    // The Q2 options corresponding to the Q1 options    
    teacherLists = {
      C1 : 'T1,T3,T5',
      C2 : 'T1,T2,T3,T4',
      C3 : 'T2,T3,T4,T5',
      C4 : 'T1,T4,T6'
    };
 
    // Identify this question
    var thisQuestion = $('#question{QID}')
 
    // The checked option in Q1
    var q1Ans = '{Q1}';
 
    // Hide all of the teachers
    $('.answer-item', thisQuestion).hide();
 
    // Now show the appropriate ones
    $(teacherLists[q1Ans].split(',')).each(function(i){
      $('input.radio[id$="'+{QID}+this+'"]').closest('.answer-item').show();
    });
 
    // Uncheck all hidden radios (in case page has been seen before)

Hi!

I have a similar situation. I have tried to use the script that you shared and it didn't work (once you tick a certain answer in q1 it doesn't modify the options in Q2). I also tried to use your test survey, and it is the same result, no change. Is there anything else I should have done? Is this working only for certain versions?My version is 2.67.3+170728.

Many many thanks!

      C3 : 'T2,T3,T4,T5',
      C4 : 'T1,T4,T6'
    };
 
    // Identify this question
    var thisQuestion = $('#question{QID}')

Thank you so much! I uploaded the demo and, when I click C1 in the first question, here is what it shows in the second page. Please see the attachment with the screenshot! In the meantime I have upgraded to 2.72 version and there is the same result :(
Is there anything I should do?

Hello,
in this case - filter a single punch question on a single punch question - I have a different approach.
To be honest: I prefer out of the box solutions just because of my lack of JS-knowledge.
Okay, Tony's script here is short, straight forward and easy to understand.

Let me explain:
Between the two single questions (here: course Q1 and teacher Q2) I insert an equation and a multiple question M1 (both hidden).
The multiple question with exactly the same answer options and codes as the second single ("Teachers") is used to be the matrix filter.

By the equation I preset the multiple question: e.g.
{M1_T1=if((Q1=="C1") OR (Q1=="C3"),"Y","")}

{M1_T2=if((Q1=="C2") OR (Q1=="C4") OR (Q1=="C5"),"Y","")}
...

And the matrix filter of Q2 is M1.

Best reqards
Joffm
