  Hi Caroline,

  So you have a structure somewhat like this, right?

  big_loop
  - big_sequence
  - - small_loop
  - - - small_sequence

  And you want the big_loop to run the big_sequence in randomized order. Do I understand that correctly? If so, it should work simply by setting order of big_loop to random.

  If this doesn't work for you, or if I have misunderstood the question, please let me know!

  Cheers,
  Sebastiaan

  Thanks for the quick reply, Sebastian. I guess you misunderstood me a little or I didn't explain too well. My structure is the following:

  big_loop
  - big_sequence
  -- small_loop 1
  --- small_sequence 1
  --small_loop 2
  --- small_sequence 2

  and I want small_sequence 1 and small_sequence 2 randomized, so it looks approximately like this:

  small_sequence 2
  small_sequence 1
  small_sequence 2
  small_sequence 2
  small_sequence 1
  small_sequence 2
  ...

  At the moment the structure of small_sequence 1 and 2 is alternating.
  In the end, I want to show each sequence 5 times in randomized order. The thing is, that the big_loop is already set to random and it doesn't work somehow. Hope you can tell me what I did wrong.

  Regards, Caroline

  Ah, I see now. The easiest way to achieve this is probably to add a variable myorder to the big_loop with the values 1 and 2. Then you add the two possible orders to the big_sequence with conditional statements, like so:

  big_sequence
  - small_loop_1 (run if '[myorder] = 1')
  - small_loop_2 (run if '[myorder] = 1')
  - small_loop_2 (run if '[myorder] = 2')
  - small_loop_1 (run if '[myorder] = 2')

  Does that make sense? I added a simple example as a gist on GitHub: link
