shuffling blocks in just one pafe of my questionnaire

Question

I want to show a scenario to each participant randomly and after that it records which scenario was shown and in the next page of my questionnaire I want to shuffle blocks. each block contains an explanation about a disorder and after that it asks two questions. Please pay attention that I just want to shuffle the order of one page blocks when showing not randomizing all questions or pages.

Answer 1

after that it records which scenario was shown

I strongly recommend that you first record which scenario to show (use a random generator) and then present the proper scenario. But, as you wrote, this is not your question :)

Regarding the random block order, please start with this manual: Rotate Pages. It referes to block of pages, as well.
