ArgumentException: Index out of bounds. Help?

Current script, I am trying to add a touch feature to add money.

 public class AddReducePlayerMoney : MonoBehaviour
 {
     public int money;
     public GameObject cam;
 
     void Update()
     {
         Touch myTouch = Input.GetTouch(1);
         
 
         Touch[] myTouches = Input.touches;
         for(int i = 1; i < Input.touchCount; i++)
         {
             if (Input.GetButtonDown("Fire1"))
             {
                 cam.GetComponent<PlayerMoney>().addMoney(5);
             }
 
             if (Input.GetButtonDown("Fire2"))
             {
                 cam.GetComponent<PlayerMoney>().subtractMoney(5);
             }
         }
     }
 }
