Replacing every other comma in Selected Choices piped text

Question

I am creating a survey on which respondents can select multiple choices from a long list of names. Each possible choice is in the format of "LastName, FirstName."  I would like to show respondents a list of their selections for review before submitting the survey.

I created a static content text question using the piped text, ${q://QID2/ChoiceGroup/SelectedChoices}, to display the selected choices. This displays the selected choices as a long comma separated string (i.e., "LastName1, FirstName1, LastName2, FirstName2,...). I tried to custom code a function to replace the commas with line breaks using guidance provided here: https://www.qualtrics.com/community/discussion/198/how-to-change-the-separator-for-piped-text

My issue is that this replaces every comma, so, instead of:

LastName1, FirstName1
LastName2, FirstName2
...

I end up with:

LastName1
FirstName1
LastName2
FirstName2
...

Can anyone provide advice on how to replace every other comma?

Thank you so much for any help you might be able to provide.

Hello @lignecpq ,Step1: Make a embedded data(answer) in survey flow before the questionStep2: Paste the below code in the multichoice question, "Add Javascript"(OnReady) option. jQuery(document).on('change', function(){ var ans=[]; jQuery("input:checkbox:checked").each(function(){ ans.push(jQuery(this).parent().find("label > span").text()); }); var s=""; for(var i=0;i<=ans.length-1;i++){ s=s+ans[i]+ '
'; } Qualtrics.SurveyEngine.setEmbeddedData( 'answer',s ); });Step3: Now pipe embedded data "answer" wherever required
