I'm running a study that starts in Inquisit and ends in Quatrlics and I'd like to send subject IDs from Inquisit to Qualtrics. 
The Inquisit instructions for doing this are at the bottom of this page:

The problem I'm having is that when I run the Inquisit study, it doesn't send a unique subject ID to Qualtrics. The url that is sent looks something like this:

   http://www.surveysrus.com/coolsurvey/part2.html?subjectid=<%script.subjectid%>

When I imagine that the url should look something like this (for subject number 1):

   http://www.surveysrus.com/coolsurvey/part2.html?subjectid=1

Has something gone wrong? Why isn't the subjectid code being replaced with the particular subject number when I run an Inquisit study?
Thanks.
