How can i make this work?

I have an animbp of a horse and the main player when a horse is spawned it is possesed instantly, through the horse animbp i want to get the speed from it and thats how i show the speed in a blendspace for the player and somehow retrieve it in my player animbp however every time i try this it fails saying that it has accessed nothing. Can someone help me to find out how to do this.

This is the horse speed: here
This is the horse spawn code: here
This is where the horse spawned goes to: here
(all blueprint ue links)

in simple terms what i want to do is get the horses speed from 1 animbp and get that speed and use it to set a blendspace in another animbp.

use the horse class movement component → Get velocity → length = speed
