Animation Blueprint and State Machine Errors

Hey Everyone,

So I am trying to follow along with these two tutorials and setup animation blueprints and state machines for my fps game.

But I have been getting these errors and am kinda stuck.
I attached a couple screenshots to show what I am coming across.
Any help is appreciated and if you need more screenshots I can take some more as well.

My end goal is to be able to have the character I have in there be able to walk on the surface of my environment. So if have any more advice as well on if I need to do anything else besides fixing those errors then that’d be fantastic as well.
