Why is my character automatically invalid?

Hey all,

My blueprint is here:

This is the walking BS I am using, I replaced it with a simple walk forward anim and that doesn’t work either. My character just glides around in the idle pose?

I don’t understand how my character is invalid, as seen I have put a print string in place and even when I drop the character into my game, it is still invalid. Is there anything here I have done wrong?

Thank you
