(use whaetver field names Pardot expects)

Step3: Add a Web Service Task

Thank you for the fast reply.

In Step 2. I am not able to add the email field and select the value from the question. Is that correct?

Also, in one question, I would like to get the selected values written in one pardot field. I have now put the field three times by selecting the different ${q://QID54/ChoiceDescription/1} to ${q://QID54/ChoiceDescription/3} in the key-value pairs. Is that correct? Or should it rather be selected choices?
