Custom Character Animation not working (Should be easy to fix)

Hey All, I’m trying to create a custom character walking animation. I made a test animation in the video below. I created the animation and it seems to work however, when I click play and UE loads the game, the animation is not playing. I must be missing some simple step but cannot figure out what it is. I’ve spent the last 2 hours trying to find tutorials but there aren’t many that show how to create new animations from scratch. Any help would be great!
