Only 2 out of 4 Objects ever spawn... Why ?(Closed)

I'm using the following script to spawn my weapons in game. I have 4 weapons and 4 spawn locations. A weapon will always spawn in all 4 locations BUT its only ever 'wep03' or 'wep04' never 'wep01' or 'wep02' I must have ran it 60-70 times (no exaggeration) and never had anything but the same 2 weapons.

 //Weapon prefabs to spawn
 var wep01 : GameObject;
 var wep02 : GameObject;
 var wep03 : GameObject;
 var wep04 : GameObject;
 
 //Spawn points
 var spawnPoint1 : Transform;
 var spawnPoint2 : Transform;
 var spawnPoint3 : Transform;
 var spawnPoint4 : Transform;
 
 function Start()
 {
     SpawnWeapons(); // Run SpawnWeapons coroutine
 }
 
 function SpawnWeapons()
 {
     for(var i=0;i<4;i++) // Run loop 4 times
     {
         var random1 : int = Random.Range(0,4);
 
         switch (random1)
         {
             case (0):
             var spawnWep1 = Instantiate(wep01);
             switch (i)
         {
             case (0):
             spawnWep1.transform.position = new Vector3(spawnPoint1.transform.position.x, spawnPoint1.transform.position.y, spawnPoint1.transform.position.z);
             spawnWep1.transform.tag = "Weapon01";  
             break;
             case (1):
             spawnWep1.transform.position = new Vector3(spawnPoint2.transform.position.x, spawnPoint2.transform.position.y, spawnPoint2.transform.position.z);
             spawnWep1.transform.tag = "Weapon02";  
             break;
             case (2):

         }
             break;
         }
 
     }
 
 }

What the hell am I doing wrong?

(The script is in JavaScript and please reply as though your explaining it to a 5 year old...lol)

Any help is much appreciated !
