give instantiated objects positions from from objects in list

hi!

i want to instantiate an object when pressed play. therefore i have a few different empty objects in the game that should give the instantiated objects the positions, where they could be placed. it should be random so that the instatiated objects will be placed at different places everytime i press start. i can not get the code right for this. what have i written wrong? could anybody please help me? thank you!

here is my code:

public var instPrefab : Transform; public var instAmount : int = 5; public var instRange : Vector3 = Vector3( 5, 0, 2 ); var instantiatePoints : List.;

function SpawnObjects() { instantiatePoints = new List.(GameObject.FindGameObjectsWithTag("InstantiatePoints"));

  var instPosition : Vector3;
 
  for (var i : int = 0; i < instAmount; i++)
  {
   for (var points in instantiatePoints)
   {
   for (var xi : int = 0; xi < points; xi++)
   {
     xi = Mathf.Round(Random.value * (instantiatePoints.length-1));
     instPosition = points[xi].transform.position;
     Instantiate (instPrefab, instPosition, Quaternion.identity);
   }
   }
