Animations don't work properly, please help

So guys, I was setting up a third person controller with the standard Player Animations of UE 4.25 of the marketplace.
And I watched this tutorial: UE4 Third Person Tutorial - 5 Animating the Character - YouTube
But something isn’t working, it’s the animations, if I walk the animation is played but the rest of the animations like walking backwards, left or right don’t work at all,

Here is a Image of the Blueprint where I think the error comes from:

I think it’s this section of the blueprint, because in the tutorial video, he could plug in the set speed into the calculate direction, if somebody could help please let me know as fast as possible.

Thanks man, it worked thanks a lot!
