Hi guys! I want to make a survey such that:
- participants can go back to previous questions: this is already achieved through [Survey Option] - [back button]
- participants can see their selected answers but CANNOT change them
I found this thread very helpful https://www.qualtrics.com/community/discussion/3848/restrict-changing-past-answers which used a genius way that somehow "freeze" a question when the "next" button on that page is clicked.
It basically defines a piece of embedded data "Flag1" as an indicator, and

Does anyone have any suggestions?
