Problems with instanstiating and raycasting

I have no clue why this isnt working. ive seen it like tthis in manuals and videos. Please help. Probably a rookie mistake but whatever, im at a loss.

 using UnityEngine;
 using System.Collections;
 
 public class MouseBehaviour : MonoBehaviour {
 
 GameObject ArrowPrefab;
 
 
     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
         void Update () {
         Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
         RaycastHit hit;
     
         if(Physics.Raycast(ray, out hit, 100)){
         Instantiate(ArrowPrefab, hit, Quaternion (0, 5, 0));
             Debug.DrawLine(ray.origin, hit.point, Color.blue);
             
         }
     }
 }
