Linking parameter from Qualtrics through URL
I have a very basic question that is driving me crazy (I have no coding experience, I apologize if I am using the wrong terms). I followed these directions https://solowiki.services.universiteitleiden.nl/index.php?title=Qualtrics_linking to link from a Qualtrics survey to an OSWeb experiment on JATOS. Everything works, except on the OSWeb feedback screen, the value of the variable says "unknown" rather than replacing it with the value from Qualtrics. What am I missing?
