I have an error in my Array, but i couldnt figure out why it was null. What am I doing wrong?

Error
NullReferenceException: Object reference not set to an instance of an object

The object that i have placed in Scroller, has 4 child game objects (planes) under it. The error states that its a problem with where I am setting the values of the levels array;

please help!

using System;


[Serializable]
public class Levels 
{
	public GameObject levelImage;
	public GameObject locked;
	public bool isLocked;
}

public class LevelSelectMenu : MonoBehaviour {

public GameObject scroller;
	public Levels[] levels;

void Awake ()
{
if (scroller && levels.Length == 0)
		{
			
			int children = scroller.transform.childCount;
			print (children);
			levels = new Levels[children];
			for (int i = 0; i < children; i++ )
			{
				levels*.levelImage = scroller.transform.GetChild(i).gameObject;*

levels_.locked = levels*.levelImage.transform.GetChild(i).gameObject;
levels.isLocked = GlobalState.levelStats.locked;
}
}
}
}*_

you kinda gotta do that differently.

levels = new Levels[children];

wont work as this does not correctly initialize the array

for(int i = 0; i < children; i++)
{
levels *= new Levels();*

}
this will correctly initialize the array for you.
