Exchanging information with unipark

Hi,

does someone have information/experience on how to correctly redirect participants from a unipark survey to psytoolkit and back?

Getting to psytoolkit and doing the task embedded in the psytoolkit survey works perfectly,

but redirecting back to the correct part of the unipark survey doesn't. I assume that the problem lies in the fact that the  so-called 'return ticket' is not correctly attached,

but I don't know how to solve this problem.

Thank you so much!
