Inquisit should handle alphanumeric IDs just fine.
Even if the script expects a numeric id? E.g.
/ subjects = (1 of 2)
/ subjects = (2 of 2)
Just asking out of general interest... BTW, Sean, can you confirm this?
I think the trick is to always start with the survey app. Have your
participants start with a Qualtrics survey page that e.g. contains
general information about the research they're about to participate in.
Qualtrics will do it's magic and generate a subject id. After the info
page, have Qualtrics redirect participants to the Inquisit page. Set
Inquisit up to use the id generated by Qualtrics as subject number.
Then let Inquisit redirect participants back to Qualtrics via the
finishpage settings to complete the 'real' Qualtrics survey. Someone
please correct me if I'm wrong.
