I'm new and I don't know how to fix this problem

so i was following this guy’s tutorial and managed to follow his tutorial from his 4.9 version to my 4.17. at 4:00 he fixed something to print a string multiple times. I did that but it doesn’t change anything. Also, why is my client side only sphere and not a player? Here is the screenshot I’m new to this so don’t know what to do or what I’ve done. I also posted this on answerhub and the comments section on the video. But no one answered me yet.
