Fail to read second URL information to expInfo


From the URL to ExpInfo I cannot read two variables

In my study I have 8 counterbalance conditions that are embedded sequentially for each participant number (%1, %2 etc.). To get the subjects evenly into the conditions, I use, which assigns the numbers to the subjects in ascending order (participant in expInfo =1, 2, 3 … etc.).
Everything works, but in order to reward the subjects through an external portal, I also need to add a “token” variable to the link.

The moment I add the token to the experiment link, the number of the subject stops being automatically read and assigned.

No matter how I combine, I can’t read two variables from the link. Always only one: token or participant.

Maybe some of you have also encountered this, I would appreciate it
