"paste on" block not working


I have a problem using the "paste on" block. I tried using out this project: https://snap.berkeley.edu/snap/snap.html#present:Username=s_federici&ProjectName=paste%20on

I saw no effect. Any ideas?

The sprite that is pasting onto something must have a costume, not the turtle. For example, I was able to paste the circle sprite onto the square sprite

But not the turtle sprite.

@ego-lay_atman-bay Thank you. Problem solved.
