Third Person Shooting Script Stopped Working

So about a week ago I made a shooting script for my third person shooter,

 using UnityEngine;
 using System.Collections;
 
 public class ShootingScript : MonoBehaviour {
 
     public Transform bulletSpawn;
     RaycastHit hit;
     public float range;
     public Rigidbody bullet;
     public float force;
     public Transform raycastStart;
     Vector3 foundHit;
 
 
     // Update is called once per frame
     void Update () {
 
             bulletSpawn.LookAt(foundHit);
             Raycast();
             if(Input.GetMouseButtonDown(1))
             {
                 Shoot();
             }
 
     }
 
     void Shoot()
     {
 
             Rigidbody clone;
             clone = Instantiate(bullet, bulletSpawn.transform.position, bulletSpawn.transform.rotation) as Rigidbody;
             clone.velocity = bulletSpawn.transform.TransformDirection(Vector3.forward * force);
 
     }
 
     void Raycast()
     {
 
             if(Physics.Raycast(raycastStart.transform.position,raycastStart.transform.forward, out hit, range))
             {
                 foundHit = hit.point;
                 
             }
 
     }
 
 }
 

and when I played my game today, the bullet wasn't spawning. Bullet Spawn is still looking at the foundhit point, but when i hit left mouse, no bullet comes out. So I know that the problem is in the Shoot() void, but I can't find anything wrong. There is nothing in the console comin up about this and all variables are assigned. Can anyone help me?
