Hi, 

I have an experiment set up so it directs from Qualtrics to Inquisit back to Qualtrics. I have the survey id set up following the instructions from here: https://www.millisecond.com/support/docs/v5/html/howto/interopsurveys.htm , which works perfectly. However after directing from Inquisit to Qualtrics - to the secondary Qualtrics survey, the same survey id is not carried over and a new one is generated. 

Does anyone know why this would be occurring? And how it could be set up so the same survey id is carried throughout?

Thanks!
