no, this is a mess.

here's the script, fixed with notes. Make sure you read it and understand what is happening :

 // this is the bullet that is copied and cloned
 // it need to be a prefab with a rigidbody
 // it needs to then be dropped here in the Inspector
 var bulletPrefab : Rigidbody; 
 
 // this is the force applied when the bullet is instantiated
 var initialForce : float = 200.0;
 
 function Start () {
 
 }
 
 function Update() 
 {
     // check if Jump OR Space has been pressed
     // OR is written like this ||
     // e.g. if ( something == 1 || anotherthing == 2 ) 
      
     if ( Input.GetButtonDown("Jump") || (Input.GetKeyDown(KeyCode.Space) )
     {
         var bulletClone : Rigidbody; // this is the clone of the bullet
         bulletClone = Instantiate( bulletPrefab, transform.position, transform.rotation );
         
         // push the bullet when it is created ** note ForceMode.Impulse
         bulletClone.AddForce( bulletClone.transform.forward * initialForce, ForceMode.Impulse );
     }
 }
