trying to add rarity to items, don't know whats wrong with this script

 #pragma strict
 
 var Health = 100;
      
 var Enemy : Transform;
      
 var EnemyDrop : Transform;
      
 var EnemyDrop2 : Transform;
      
 var EnemyDrop3 : Transform;
 
 var RandomPick : int;
      
      
      
 function ApplyDamage (TheDamage : int){
 
     Health -= TheDamage;
      
     if (Health <= 0){
 
         Dead ();
      
     }
 }
      
 function Dead(){
     RandomPick = Random.Range(1,40);
     {
     if(randomPick >= 1 && randomPick <= 10){
         var Item1 : Vector3 = Vector3(Random.Range(-1.0,1.0),0, Random.Range(-1.0,1.0));
         Instantiate(EnemyDrop, Enemy.transform.position + Vector3(0,0,0) + Item1, Quaternion.identity);
         Debug.Log("Chose pos 1");
     }
      
     else if(randomPick >= 11 && randomPick <= 20){
         var Item2 : Vector3 = Vector3(Random.Range(-1.0,1.0),0, Random.Range(-1.0,1.0));
         Instantiate(EnemyDrop2, Enemy.transform.position + Vector3(0,0,0) + Item2, Quaternion.identity);
         Debug.Log("Chose pos 2");
     }
      
     else if(randomPick >= 21 && randomPick <= 30){
         var Item3 : Vector3 = Vector3(Random.Range(-1.0,1.0),0, Random.Range(-1.0,1.0));
         Instantiate(EnemyDrop3, Enemy.transform.position + Vector3(0,0,0) + Item3, Quaternion.identity);
         Debug.Log("Chose pos 3");
     }
     Destroy (gameObject);
 }

This should work for you. Everything except the variable declaration have to be in a function.
