Can't attach FPS rifle to arms during gameplay/

I can’t get my gun to spawn to my player. I can see that the gun is in the world but it won’t spawn with my player. I believe I attached the correct nodes as I was instructed but I am having no luck.

I am following this tutorial from Unreal Sensei on creating your first fps game and have been unable to progress because of this. https://www.youtube.com/watch?v=1XjgLKrb4_M&t=8927s
