Hi! Thanks for the reply. Well, I print to console what is in prime_num in the end and it seems to be correct.
I don’t think the problem is with the randomisation, because I tried several things in the “Selected” field of the loop:
6 - doesn’t work
[6] - doesn’t work
6:10 - works
[6,7] - works
prime_num - doesn’t work
[prime_num] - doesn’t work
[prime_num, prime_num] - works.
