Millisecond Forums

I have a study hosted in sona. It sends people to qualtrics first, then milisecond, and that's where they finish and get credit. Here is what I have done so far:

1. Sona study url: https://uwmadison.co1.qualtrics.com/jfe/form/SV_bBEVTkvsNaXPv5H?id=%SURVEY_CODE%   
2. The link that participants click (generated by sona): https://uwmadison.sona-systems.com/default.aspx?p_return_experiment_id=1696                             
3. Within qualtrics survey flow, I embedded "id" (for step 1)
4. End of qualtrics link (to milisecond): https://mili2nd.co/euvb?subjectid=${e://Field/id}
5. On milisecond, the subject id is set to random selection. However it should be overwritten by the "id" right?
6. And finally, on milisecond the finish page is set to: https://uwmadison.sona-systems.com/webstudy_credit.aspx?experiment_id=1696&credit_token=85c9eade3b254378b1413cf3d66a9fb0&survey_code=<%script.subjectid%> where the subjectid should be the same as id=%SURVEY_CODE%  in the first step. 

Participants can finish the qualtrics survey and inquisit study without issue, but they are not granted credits. Could you tell me what I did wrong?
