Animation rainbow challenge

Hey, I completed the challenge, but how come there is no animation on the blackline?
Typing the code by myself doesn’t trigger it, but when I tried to copy the example from the left, it seemed to work, any thoughts?

P.S. Not sure how to add the code in here

edit: Might be some bug with the first “[” but I went underneath it and now the rainbow seems to be working :slight_smile:
