Can't get my Object reference to connect to the existing Third Person Blueprint.

I am super new to Blueprinting and it’s been frustrating. I am following a tutorial about “Shared Camera Screen” set up and the current setup I have is causing some issues:

  1. Issue is the fact that it only spawns one player instead of four (and they no player control).
  2. Issue is that I can’t connect the BP_Camera to the GetControlRotation.

Can anyone help? Here’s a screenshot and here’s the link to the video:
