Gun script reload problems

hey guys i have a qustion aboute my gun script it almost works fine But!when i dont have any bullet Clips left i can still do the reload animation when i press r and it shouls be doing that i think i know how to fix it but i cant add the code to the script becouse i triad this

 if (clips > 0) {
         clips--;
         bulletsLeft = bulletsPerClip;
         UpdateGUI();
             Reload (); = false;
     }
 }

But it does not work here is the script

 var range = 100.0;
 var fireRate = 0.05;
 var force = 10.0;
 var damage = 5.0;
 var bulletsPerClip = 40;
 var clips = 20;
 var reloadTime = 0.5;
 var muzzleFlash : Renderer;
 var bulletGUI : GUIText;
 var HandsP90 : GameObject;
 var minimumRunSpeed = 1.0;
 
 private var hitParticles : ParticleEmitter;
 private var bulletsLeft : int = 0;
 private var nextFireTime = 0.0;
 private var m_LastFrameShot = -1;
 private var machineGun : P90GunScript;

     if (hitParticles)
         hitParticles.emit = false;
     bulletsLeft = bulletsPerClip;
