Scene switching and loading problems

I am working on a platformer and I have a sprite that when it collides with the player it loads a new scene (whatever scene you tell it to load). Here is the code (C#) also I have a screenshot of the errors, Any help is greatly appreciated!

 using UnityEngine;
 using System.Collections;
 using UnityEngine.SceneManagement;
 
 public class SceneSwitchCollision : MonoBehaviour
 {
     
 
     // Use this for initialization
     void OnCollisionEnter2D (Collision2D Colider)
     {
         if (Colider.gameObject.tag == "Player") {
             SceneManager.LoadScene(string. scenePath);
         }
     }
 }
