I have a matrix table where people can choose their support among some candidates. 

Then, I want to pick the candidate with maximum support, to catch a video for people to watch. 

I have chosen to operationalize this by using JavaScript along with capturing Answers and Choices through this:

When happens is that, when someone chooses the same level of support for two candidates, Qualtrics omits the duplicate. My Javascript begins with

    var supportAnswers = "${e://Field/SupportAnswers}";
    var supportChoices = "${e://Field/SupportChoices}";

and then operationalizes a bunch of stuff with a CSV file.

Since the number of candidates varies with different cities, getting the whole vector of SupportAnswers was really good in making things similar across different “Branch Ifs”.​​​​​​​

Any ideas?
