Randomizing Routine Presentation

Standard Standalone PsychoPy3

Hi, my name is Alan I am currently building a study with 3 questions that uses a pool of 15 stimuli. I have currently put 3 routines to present each of the three different questions and a loop outside of each routine to randomly choose specific columns from the excel stimuli sheet (using RAND function). I tried putting a second loop around all 3 routine loops in hopes of randomizing the routine presentation but it did not help. To repeat I want to present the routines in a random order without having to manually rearrange them before every new experiment.

I was wondering if any of you could help?
