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?

Line 20:

if(Input.GetMouseButtonDown(1))

uses the right mouse button.

For left mouse use:
if(Input.GetMouseButtonDown(0))

Also, are lines 18 and 19 the wrong way around? Shouldn’t you call Raycast() first to find the foundHit position and then make the spawn object look at the new position?
