How do I get the Hud Box to display.

I have been trying to get this to work for about a week now, ( I KNOW NOTHING about blue printing and dont have 6 months to learn it as this is for a overdue collage assessment) When ever the Hud is called upon the game pauses but the Hud menu will not display. The HUD menu works when I dont set up a branch, But the second I set the branch up the Hud will not display upon pressing a " m "KEY.

I have been building My hud based off 4.7 content examples while using engine number 4.9. The game just freezes and requires you to hit ESC. ( This game is for a Collage project ) I have decided to make a space invaders squeal where they have reached earth.
