How do I set embedded data with Qualtrics using Javascript?

Hi TomG. Thank you for your response! Here's my code:
Qualtrics.SurveyEngine.addOnload(function()
{

});

I'm not sure what the issue is, but I would add this line before the setEmbeddedData for traits1a:
console.log("a_list array",a_list,"a_list string",a_list.join("|"));
Then check the console. Hopefully, it will give you a clue if something is wrong with a_list. If nothing is amiss try piping

${e://Field/traits1a}

https://community.qualtrics.com/XMcommunity/discussion/comment/49184#Comment_49184You don't need to pipe it to save it. Two things:

1. Check to make sure 'traits1a' is spelled exactly the same in the survey flow


2. Someone recently mentioned that a field set with setEmbeddedData() in the last question of the survey didn't get saved. I didn't quite believe it, but if your question is the last in the survey it seems that it might be a Qualtrics bug. Luckily, it is easy enough to work around. I would first try adding a survey flow branch after the block that checks the value of traits1a. I think that would fix it. If not, you can add another page.
