2D Character Sprite Animation

I'm trying to animate a sprite by cycling through multiple sprites to create an animation.
I've got everything working correctly, but for some reason it won't change the sprite anymore.
I had it working previously, but now it won't. To make sure it's not just the animation not being called, I added a rotation. The rotation works fine. I've included the animation window, I can include more if requested. Thanks so much

 

You seem to have Animation component instead of Animator. Animation is legacy and doesn't support sprite animation.
