Multiple random spawns from an array

Hi, I am trying to have 36 different spawn points and each spawns a random item out of a list of 10. Right now, I have it so that the game randomly picks an item and has that one item spawn at all 36 spawns. How do I make it so that my Instantiate and array lists make a chance for a random item to spawn at all 36 spawns.

Code:

 public var Block : Transform [];
 public var objectToSpawn : GameObject [];
 
 var TimeToSpawn : int;
 var RandomNumber : int;
 var BuildingChoice : int;
 BuildingChoice = Random.Range(1.0, 10.0);
 TimeToSpawn = Random.Range(1.0,3.0);
 
 
 function Update () 
 {
 if(Input.GetKeyDown(KeyCode.Space)) 
 {
 Invoke ("spawnObject", TimeToSpawn); /
 }
 }
 
 
 
 function Start () 
 {
 }
 
 function spawnObject()
 {
     for(var n = 0; n < 36; n++)
     {
     Instantiate (objectToSpawn[BuildingChoice], Block[n].position, Block[n].rotation); 
     }
 }
