Blueprint Comms Not Working Invalid

I have a player that can fire some projectiles, but I can’t seem to get the projectiles to communicate with the player blueprint.

This is how the projectile is spawned in. Basically by IS INPUT HELD DOWN

This is what the projectiles have. On begin play it should trigger an event in the DefaultPlayer blueprint

This is what I am trying to get it to trigger, however

This is what happens ingame when the projectile is spawned
