So I've come up with.
game.Players.ChildAdded.LocalPlayer.Username = N
Will this save the Child added's Name to the letter N?
So i can call it back?
And I've confused myself with how to call it back so How can I call back the username?
Ive changed it actually would it be N = game.Players.ChildAdded.(MaybeLocalPlayer).Username
Is that right?

What? This is the most confusing thing ever... So do you want the players name to be Person with an n so it is like Personn or do you want it to be a variable in which it is in? Cause you would do local N = Game.Player.LocalPlayer
No I'd like to be able to call back a LocalPlayer's Username.
