Hi Kennedy_Isip_KantarKennedy_Isip,
Can you use display logic to solve this? eg: display Q3 if the answer to Q2 = "Red".
When setting display logic there is also an "In Page" option which will allow the survey to continually check whether your display condition in the same page is true/false, and then respond accordingly.
Best of luck!

Hi bgooldfed,
I need the jquery/javascript condition considering that I'm triggering a pop-up form. The idea is that when Q1 answers "Yes", there's a pop-up form asking for consent from the respondent.

Hi Kennedy_Isip,
So when the user clicks the "Yes" option, your modal appears, correct? If so, something like this should suffice:
//replace #yes with the ID of the "Yes" option
//replace #modal with the ID of the modal on your page
jQuery("#yes").click(function(){
    jQuery("#modal").modal();
  });
Good luck!
