Show random question

Hi everybody,
I am new here, but glide seems to work OK. I am building a yearplanner for my school, but more interesting I am trying to build a speeddate app for my class.
Seems easy. In excel there is only one column with a lot of questions.
if the app starts it has to show a random question. Then, button to random sort it should show an other question. Seems easy. However, I am missing something or not sure what random sort means. Any help?

This app might give you some idea.
