How do I create random frame?

Hello there. I'm using this tutorial for my first game and want to create random frames.

Have tried random and int(random) already:

but only one frame is created - second one, with a shrimp.

Animation speed = 0, checked already.

Haven't found an answer while googling, sorry, so starting this tread.

What am I doing wrong?

You are setting the animation speed instead of the bullet speed.

Thanks for your help! Got my mistake, now everything works perfectly)
