Ok so there is a lot of stuff in those blueprints that are doing nothing.
The first 2 images do absolutely nothing at all so just delete those.
Also on your event “actorBeginOverlap” you will want to make sure the other actor is the player.
But the main error here is that you are destroying the actor before the “Add Scores” function is called which means it doesn’t even exist to call that function. Destroy the actor after add scores is called, preferably with a small delay node in between like 0.1 second or so just to make sure.
