How to spawn diferent game objects in an array?

I have been trying for hours to get this to work and I have not come up with the answer searching either. What I am try to do in JScript: Spawn different replacements after my enemies are destroyed. For example when it is destroyed I want an explosion to instantiate in its place and and sometimes a wreakage as well. Here is the code I am using but nothing happens after an enemy is destroyed:

 #pragma strict
 
 var hp : float;
 var replacementSpawn : GameObject[];
 var replacement : GameObject;
 
 //Take Damage Function
 //Subtract damage from hp
 
 function TakeDamage( damage : float )
 {
     hp = hp - damage;
     if(hp <= 0)
     {
         
             var i : float = 0;
             while( i < replacementSpawn.Length)
             {
             Instantiate (replacement, replacementSpawn[i].transform.position, replacementSpawn[i].transform.rotation);
             i++;
             }
             
             
         Network.Destroy(gameObject);
     }
 
 }
