Fire Rate Not Changing (C#)

So I have been making a top-down shooter style game, and it has been going pretty well, other than the fact that when I change the value of “timeBetweenShots” (the fire rate variable) it doesn’t change the fire rate at all, no matter if I set it at 0.001, 0.1, 1, or even 100. It stays a constant line of bullets. I have tried changing around the script a bit, but nothing changes. Please look at my script, and tell me what is wrong if you can.

using UnityEngine;
using System.Collections;

public class GunFire : MonoBehaviour {

	public bool isFiring;

	public BulletScript bullet;
	public float bulletSpeed;

	public float timeBetweenShots;
	private float shotCounter;

	public Transform firePoint;

	// Use this for initialization
	void Start () 
	// Update is called once per frame
	void Update () 
			shotCounter -= Time.deltaTime;
			if (shotCounter <= 0) 
				shotCounter = timeBetweenShots;
				BulletScript newBullet = Instantiate (bullet, firePoint.position, firePoint.rotation) as BulletScript;
				newBullet.speed = bulletSpeed;
			else {
				shotCounter = 0;

From If Else of shotCounter just remove the else block because it will never let the If block to execute

Accept if it did the trick
