HELP! I can't get Arcade_shooter to restart when dead

Hi. I’ve read various posts before me. I’m doing the “Learn Unreal in 24 hours” book. I’m in Hour 21 and I’m stuck. I can’t get the arcade shooter to restart when it collides with the meteors. the ship explodes and the game sits. I get figure out how to add “restart Game”. I type the words “restart game” and it does work. I’ve tried and tried different methods. I’m sure someone has already figured it out…can you help???
here is the screenshot. done to the book. thank you in advance.
