[c#]collision script not working

I have a script that takes collision against walls and if i get to the goal but it does not work I want it to let me drag and drop in the inspector to choose where my player gets teleported

 using UnityEngine;
 using System.Collections;
 
 public class Collision : MonoBehaviour {
     void OnCollisionEnter2D(Collision2D coll,Transform NextSpawn) {
         if 
         (coll.gameObject.tag == "Lava")
         Application.LoadLevel (Application.loadedLevel);
         else if 
         (coll.gameObject.tag == "Victory")
                 Transform.position = (NextSpawn); 
     }
 }
