Need help with Anim Blueprint

I have been following a guide on the website.
(This one specifically
When I get to step 5, I get an error that it does not compile. From what I understand it just won’t work the way it is intended as per the BP. I need help figuring out what is going on and why I cannot get it to work. It doesn’t fix itself after I complete all the steps all the way through the guide either. I have also tried to go back and double check, even going so far as to restart entirely with no success. Can anyone figure out what I need to do?

Also I should add that it doesn’t compile after I attach and complete the Walk_BS step, and that I am using the Animation Starter Pack from the market.

I will attach pictures of what I have done and set up to maybe help with the issue.

Thank you.
