Can't attach player to object?

Hello. I’ve tried several things now and can’t figure out what I’m doing wrong. I want to attach the player to this other object when the player is in the trigger volume to allow for it. I have set everything up on both objects. The player is spawned via a Game Start with the pawn class set to my custom player controller blueprint that inherits from “Character”. I’ve used breakpoints to verify events and variable are being set correctly and there are no warning or errors on simulation. Can anyone help me understand what I’ve done wrong here?

Her’s an image of the node graph for the logic in my player controller script.
