Overlay Widget isn't displaying

OK, so I am creating a game with lasers, currently, the lasers will destroy any box actor that collides with them as they should. Now I am trying to set-up these lasers so that when the player collides into them, the screen will bring up a red overlay widget, and then after a few seconds restart the level.

I have trigger boxes set up throughout the level that span the area of the laser, so the character isn’t actually colliding into the laser, but a trigger box.

Level BP calling death event in player:

And here is the character’s response:

I know that it’s only the HUD not being brought up, not the character not responding, because when he collides, the level will still restart… so what’s going on?
