Hi,
Since in-page display logic is disabled for slider questions, I used the following JavaScript code to enable the slider question to appear on the same page conditional on the response in the first multiple choice question:
Qualtrics.SurveyEngine.addOnload(function()
{
// hide next question from start
  jQuery("#QID28").hide('.slider');
  // when current question is clicked
  this.questionclick = function(event, element) { 
    // create variable with clicked answer and check
    var selectedChoice = this.getSelectedChoices()
    console.log(selectedChoice) 
    // show next question if condition is met
    if (selectedChoice == "1") {
      jQuery("#QID28").show('.slider');
    }  
    // in case answer is switched, hide again
      else {
        jQuery("#QID28").hide('.slider');
    }}
});

Two issues arise:

• First, the slider question becomes hidden again if the user tries to procced to the next page without having moved the slider


• Second, and more importantly, about 1/10th of the time, the slider width (the response that it, not the question) becomes too narrow - sometimes it even collapses altogether and simply becomes a single point that is unusable, making it impossible to proceed to the next page:
