Normally you'll want your survey / recruiting platform to generate that unique id and then have it forward that to Inquisit via an URL query parameter -- most, if not all, platforms should support this. You'll then have Inquisit use that id as subject identifier, which will make sure it's recorded in the data file and thus enabling you to match data between platforms -- all without your participants ever needing to write some code down and inputting it elsewhere. You'll find the general way to go about this covered in the "How to interoperate Inquisit with online survey packages" topic in the Inquisit documentation.

Hi Dave,
I am in the exact situation that you describe above.  I had set this up and everything was working perfectly.  In Qualtrics I had participants redirected to INQUISIT using the following link:  http://research.millisecond.com/maf1974/AgeIAT.web&subject=${e://Field/ResponseID}

However, I then used Qualtrics Panel services to recruit a bunch of participants for me and they said I need to set up a different URL parameter called "gid".  This "gid" is the Panel providers' unique ID code for each participant so that they can track which ones have completed the entire survey for payment purposes.  Therefore, instead of the perfectly functional redirection link in my first paragraph above, I am now being instructed by Qualtrics to use the following link:  http://research.millisecond.com/maf1974/AgeIAT.web&gid=${e://Field/gid}

When I do this, the redirection takes participants to the INQUISIT site and correctly appends the gid value onto the end of the URL, but the IAT link is broken and a "page not found" message id displayed.  I think this is because I have removed the word "subject" from the link, or perhaps because the value of the gid paramerter is not recognised by INQUISIT...?  The gid parameter value is VERY long e.g.,  gid=US200007-1234-5678-9101112-13141516-17181920-aBcDefG

Can you provide any insight as to why the gid URL is being piped correctly by Qualtrics but the INQUISIT IAT launch page link is broken?

Thanks
Mike

No. The problem is that the query parameter part of your link is broken / invalid:

The *first* query parameter in a given URL is indicated by a question mark (?). Any *additional* query parameters after that are prefixed with &.

The link you posted is

It ought to be
