Wrote a script for Shooting, reloading and to display the AMMO in a GUIText

This is the script, When ever I start the game It says "Assets/shoot.js(17,22): BCE0018: The name 'ammotext' does not denote a valid type('not found')" I have no Idea what to do >.>

 var sound : AudioClip; //ie_shot_gun-liminalace-770179786 soundClip
  
 var reloadSound: AudioClip; //reload soundClip
  
 var BulletSpeed = 100; //force of bullets being shot
  
 var projectile : Rigidbody; //bullet prefab goes here
  
 var bullets = 30; //amount of bullets per "clip"
  
 var totalBullets = 60; //total amount of bullets we have available
  
 var reloadTime = 3; //time to reload
  
 var reloadAmount = 10;
  
 var ammo : ammotext; //GUI text for our bullet/ammo count
  
 function Update () {
  
 Fire ();
  
 Reload ();
  
 }
  
 function Fire () {
  
 if(bullets > 0) { //if we have at least 1 bullet then we can fire
  
 if (Input.GetButtonDown("Fire1")) {
  
 var clone : Rigidbody;// Instantiate the projectile at the position and rotation of this transform
  
 clone = Instantiate(projectile, transform.position, transform.rotation);
  
 clone.velocity = transform.TransformDirection (Vector3.forward * BulletSpeed);// Give the cloned object an initial velocity along the current
  
 AudioSource.PlayClipAtPoint(sound, transform.position, 1);                     // object's Z axis
  
 bullets -=1; //subtracts one bullet per fire sequence
  
 }
  
 }
  
 }
  
 function Reload () {
  
 if(bullets < 1) {    //if we have less than 1 bullet then we can reload
  
 if(Input.GetKeyDown("r")) {
  
 AudioSource.PlayClipAtPoint(reloadSound, transform.position, 1); //plays reload soundclip
  
 yield WaitForSeconds(reloadTime); //waits for "reloadTime" before adding bullets
  
 bullets += reloadAmount; //adds 3 bullets to our "clip"
  
 totalBullets -= reloadAmount; //subtracts 3 bullets from our totalBullets amount
  
 }
  
 }
  
 }
  
 function OnGUI () {
  
 ammo.text = "bullets: " + bullets + "/" +  totalBullets.ToString();
  
 }
