I am trying to modify some custom code for a two-knob slider (found here) so that I can set embedded data from the 2 points that are selected with the knobs. I have 'Q1_min' and 'Q1_max" set as blank embedded data fields in my survey flow, but I can't get this code to write anything to those embedded data fields. I am very inexperienced with javascript, so any help (especially with explicit explanation) is much appreciated. Here is what I have so far:



Qualtrics.SurveyEngine.addOnload(function()

{

var surface;

var cnst = 1;

var min;

var max;

// Sets the sliders parameters and starting values

$("#research-slider").slider({ id: "research-slider", min: 0, max: 100, range: true, value: [0, 100]});

// variable to store in surface area when user has stopped sliding

var surface, currentResponse;

$("#research-slider").on("slideStop", function(slideEvt) {

surface = slideEvt.value;

document.getElementById("minimum").innerHTML = surface[0];

document.getElementById("maximum").innerHTML = surface[1];

document.getElementById("range").innerHTML = (surface[1]- surface[0])/cnst ;

min = surface[0];

max = surface[1];

});



Qualtrics.SurveyEngine.setEmbeddedData( 'Q1_min', min);

Qualtrics.SurveyEngine.setEmbeddedData( 'Q1_max', max);



$('NextButton').onclick = function (event) {

// and now run the event that the normal next button is supposed to do

Qualtrics.SurveyEngine.navClick(event, 'NextButton')

}







})
