I am trying to do approximately the same. At the end of my experiment, the participants have to answer some questions in Qualtrics (I have a so called anonymous link) but I want to link the answers from qualtrics to the appropriate experiment participant/data and I don’t know how… I tried this:
$“url/” + expInfo[‘participant’]
but this doesn’t work.
If I add the link in “completed url” without the “+…” it works but it doesn’t help to link the two together.
