LoadLevelAdditive and JavaScript variables

I am using LoadLevelAdditive and I have two scenes.

How can I get GameObject from scene one to my JavaScript in scene zero?

Like this:
Scene 0: JavaScript:
var object : GameObject;

Scene 1: object (GameObject)

I have tested "FindWithTag" and "GameObject.Find" but without luck.

 

try finding the object type

var other : OtherScript = FindObjectOfType(OtherScript);
other.DoSomething();

as described here:
