Actor not animating

Hi, so I followed tshirtbooths tutorial on how to make a basic platform game movement

I did the exact same thing as the tutorial, except added an animate attribute after the movement attributes.
So I have:
When right = true, left = false
animate(then the 3 frames for when it is going right)
self.change attribute -> linear velocity -> 200 (makes him move right at 200 speed)
I have the same thing for left button. My character does not animate at all. He just moves left and right with the static image o_0. My right animation only has 3 frames, and same with my left animation.

There's another Platformer template using animation in the GS Creator New section, which I seem to remember does it slightly differently than tshirtbooth; maybe worth checking out.
