[Solved]Two Player Error

So I have made this really simple player script, which gets its controls from a Hashtable I have set up in a different script. The player always moves to the right and the controls will make it change direction. I have set up 4 different control schemes for 4 different players. When I only have 1 player in the scene it works fine, I can assign the player a player number and the control scheme changes depending on player number. Everything works perfectly. However when I duplicate the player and give them 2 different player numbers, the duplicated player will not move or react to controls.

I get these errors when duplicating the player and starting the game

The 1 and 2 are a Debug.Log I put in to check that they are reciving their playernumbers correctly. However player number 2 gets a NullReference

This is the initialization code that gets executed, this is where I fetch the controls in the main Player.cs.

 void Start () {
     rigidbody = GetComponent<Rigidbody2D> ();
     controls = GetComponent<PlayerControls> ();
 
     //GET CONTROLLERS
     Debug.Log(playerNum);
     control = controls.getControls(playerNum);
     setKeys(control);
 }

and here is how the PlayerControls.cs looks like.

 void Start () {
 
     //Player1
     player1 = new Hashtable();
     player1.Add("Up", "a");
     player1.Add("Down", "d");
     player1.Add("Shoot", "s");
     player1.Add("Boost", "w");
 
     //Player2
     ....
     ....
 }
 
 public Hashtable getControls(int num) {
     if(num == 1) {
         return player1;
     } else if(num == 2) {
         return player2;
     } else if(num == 3) {
         return player3;
     } else if(num == 4) {
         return player4;
     } else {
         Debug.Log("Incorrect player number!");
         return new Hashtable();
     }
 }
