Why do you have selected rows 0. Try 0:1 to use just the first row.

Error reading ONE row from the condition file

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.
