Animations not working

I’m made and programmed the walk and run animations but they wont work, I think its because I don’t have a avatar for the animator but I don’t know how to do that. Can someone help?

Click your little figure asset’s (>) expando button. I bet you it has the avatar in there.

Except for the swimming trunks, that looks like Synty’s “Polygon Prototype” dude, specifically, the Male No-Face variant.

There is no avatar there.

Then you will either need to make one (in your model’s FBX file’s Import Settings), or go ask your asset artist to supply it.
