variable reset not working.

i'm having a bit of a stupid problem, maybe someone can notice something i haven't. whenever i shoot a bullet, i want the timer to reset whenever I shoot, but its not working.

 using UnityEngine;
 using System.Collections;
 
 public class ExperimentalMachineGun : MonoBehaviour {
 
     public Animator Fire; 
     public AudioClip MinigunFire;
     public float ProjectileSpeed;                // Reference to the player's animator component.
     public float rateOfFire;
     public bool UseTouchControl;
     public bool JoystickIsTapped;

         JoystickControlScript = GameObject.Find ("MonstercatCharBase").GetComponent<JoystickControl> ();
 
         Particles = GetComponent<ParticleSystem>();
 
         BarrelTip = GameObject.Find("BarrelTip");
 
     }
     //private bool isFiring = false
 
     void Update () {
 
         PlayerScript = GameObject.FindGameObjectWithTag("Player").GetComponentInChildren<ExperimentalDeath> ();
 
         if (ShootJoystick.GetComponent<Joystick> ().tapCount > 0){
             JoystickIsTapped = true;
         } else {
             JoystickIsTapped = false;
         }
 
         //this is a counter that tells you the time in seconds from the last projectile fired
         rateOfFireTimer += Time.deltaTime;
 
         if (UseTouchControl == false) {
             //Fire Primary Weapon. I do (1/rateOfFire) so that you can enter a number like 10 in the inspector to mean 10 per second
             if (rateOfFireTimer >= rateOfFire) {
 
                 if(Input.GetKey (KeyCode.Mouse0)){
