Custom Drag and Drop javascript not working in Qualtrics

Hi there, if you still need, I was able to get an example of Redips drag and drop to work on my end. First, head over to the General section of the survey's Look & Feel and paste the below into the Header:
 
Then, to capture the table output, head over to the Survey Flow and create an Embedded Data element at the very top of the Flow. Create an Embedded Data field called "TableContents".
Next, head to the Builder and create a Text/Graphic question. Using the Rich Content Editor's HTML/Source view "<>", paste in the below:
Please drag and drop the below options.

 

Finally, update the question's JavaScript with the below:
Qualtrics.SurveyEngine.addOnload(function()
{
/*Place your JavaScript here to run when the page loads*/

var redipsInit = REDIPS.drag.init();

});

Qualtrics.SurveyEngine.addOnReady(function()
{
/*Place your JavaScript here to run when the page is fully displayed*/

});

Qualtrics.SurveyEngine.addOnUnload(function()
{
/*Place your JavaScript here to run when the page is unloaded*/

});

Qualtrics.SurveyEngine.addOnPageSubmit(function()
{
var tbl = document.getElementById("tbl");
var content = REDIPS.drag.saveContent(tbl);
Qualtrics.SurveyEngine.setEmbeddedData("TableContents", content);

});
The output gets saved to the Embedded Data field of TableContents but will require some parsing to make sense of the drag and drop placements. The query output follows the format described here.
