an array of a class, in another array of a class

Hi,

I am trying to access an array of a class, in another array of a class. However the last 2 lines don't work, and I don't know how to do it...

class pattern{ var width: float; var number : float; var Asteroids : asteroid[]; }

 public class asteroid{
     var position : Vector3;
     var rotation : Vector3;
     var scale : Vector3;
 }
 
 var patternList : pattern[];
 
 function CreatePattern(){
 var patternList = new pattern[50];
 patternList[0] = new pattern();
 
 var patternList[0].Asteroid = new asteroid[10];
 patternList[0].Asteroid[0] = new asteroid();
