I'm running a conjoint experiment in Qualtrics adapting the code found in this repository. The respondents are shown a list of randomised attributes pertaining to a hypothetical political candidate and asked who they would vote for, given the attributes.

At the moment I'm trying to get the repository version to work before I begin to adapt it. However, I'm having trouble exporting the list of attributes which the respondent sees for my analysis. When I export the responses I've tested manually, the columns for embedded data are all blank. It's possible the code is now out of date and needs to be updated. I have absolutely no experience with Javascript and so I'm at a bit of a loss as to what the problem might be.

Any suggestions would be very welcome.

Thanks

FYI, here's what the survey flow looks like in Qualtrics Also, for what its worth, I suspect the problem is occuring in the last two sections but I reconmend you take a look at the link because its explained much better than I ever could.

// set html values in conjoint table
for(i=0;i<13;i++){
    document.getElementById(a_list[i]).innerHTML = traits_a[i];
    document.getElementById(b_list[i]).innerHTML = traits_b[i];
}

// store values as embedded data fields
Qualtrics.SurveyEngine.setEmbeddedData('traits1a', traits_a.join("|"));
Qualtrics.SurveyEngine.setEmbeddedData('traits1b', traits_b.join("|"));
