Can't get bool from a blueprint working in an other

Hello everyone,

I’m new to Unreal and especially to the visual scripting. I’m pretty confused on how to get a variable from a blueprint working in an other one.
I’m trying to get this “TouchePas” boolean set up in my HoverComponent (SceneComponent) to work in my Hover_Vehicule (PawnComponent) to finally change my “Vitesse” float. I’ve tried with CastTo, GetAllActors but nothing work or maybe I didn’t set up correctly. So can someone help me please ?
