Problem with script for changing character?

im currently in a gamecraft, and i m making a game where i need to switch from character to character in a 2d sidescrolling game and ive a few errors that need sorting out

ive only been at this for a month now so please not too much hard words

public class SwitchPlayer : MonoBehaviour { GameObject player1; GameObject player2;

 var player1Input : (Move);
 var player2Input : (Move);
 
 bool  player1Active = true;
 bool  player2Active = false;
 
 GameObject defaultCamera;
 GameObject cameraPlayer1;
 GameObject cameraPlayer2;
 
 void  Start (){
     player1Input = player1.GetComponent("(Move)");
     player2Input = player2.GetComponent("(Move)");
 }
 
 
 
 void  Update (){
     if(Input.GetKeyDown("1"))  {
        player1Active = true;
     }
 
 if(Input.GetKeyDown("2"))  {
    player2Active = true;
 }
 
 if(player1Active){
    switchToPlayer(player1Input, player2Input, cameraPlayer1);  
 }
 
 if(player2Active){
    switchToPlayer(player2Input, player1Input, cameraPlayer2);  
 }
 

}

void switchToPlayer (inputToEnable, inputToDisable, cameraLocation){

         inputToEnable.enabled = true;
 
         inputToDisable.enabled = false;
 
         defaultCamera.transform.position = cameraLocation.transform.position; //Consider lerping 
 
         defaultCamera.transform.roatation = cameraLocation.transform.rotation; //Consider lerping
 
     }

}
