Description of the problem:

I am trying to pass the following variables from Pavlovia to Qualtrics (where I have a post-task questionnaire):  
Prolific ID, study and session ID, participant number and random number, along with a list of stimuli called ‘adj\_list’.

All the variables I mentioned are taken in Pavlovia as experiment information (see screenshot below), except the list of stimuli which is created in Pavlovia throughout the task.

This is the completion URL I created to try and pass these info to my post-task questionnaire in Qualtrics, which is not working:

[https://bhampsychology.eu.qualtrics.com/jfe/form/SV\_bOUJhQD1hWDQhTf?PROLIFIC\_PID=“expInfo[‘PROLIFIC\_PID’]&PARTICIPANT\_ID=”+expInfo[‘participant’]&RAND\_ID="+expInfo[‘RAND\_ID’]&STUDY\_ID="+expInfo[‘STUDY\_ID’]&SESSION\_ID="+expInfo[‘SESSION\_ID’]&adj\_list="+adj\_list+](https://bhampsychology.eu.qualtrics.com/jfe/form/SV_bOUJhQD1hWDQhTf?PROLIFIC_PID=%22expInfo%5B'PROLIFIC_PID'%5D&PARTICIPANT_ID=%22+expInfo%5B'participant'%5D&RAND_ID=%22+expInfo%5B'RAND_ID'%5D&STUDY_ID=%22+expInfo%5B'STUDY_ID'%5D&SESSION_ID=%22+expInfo%5B'SESSION_ID'%5D&adj_list=%22+adj_list+)"

Once in Qualtrics, what I do is to set the variables as embedded data (see pic 1 below) and then insert them in the questionnaire as embedded data field (see examples in pic 2 and 3 below)

Any idea of where I am making mistakes? People can’t see the list of stimuli (adj\_list) in Qualtrics, and in the results spreadsheet I get ${e://Field/PROLIFIC\_PID} instead of the actual Prolific ID.

Many thanks for your help!
