Novice/starting coder seeks help. I need to pass a variable from one scene to the next for player selection. This loads first:

 var hit : RaycastHit;
private static var characterSelected:gameObject;

function Update () {

    // Use Raycast to pick objects that have mesh colliders attached.

    var ray = Camera.main.ScreenPointToRay (Input.mousePosition);


    if (Input.GetMouseButtonUp (0))  //Returns true during the frame the user deselects the object
    {
        if (Physics.Raycast (ray, hit, 100)) 
        {
            characterSelected:gameObject=playerAggy; //this doesn't work
            Application.LoadLevel (1);
        }
    }

    else {
    }

}

That code is going to be a component of an invisible box collider (used to detect mouse click) on each 3D player in the level selection screen . Right now for testing, I only have it on the first player(Aggy). ("playerAggy" is the name of the prefab for the player (one of three.) )

In the second scene, I try to instantiate aggy to start gameplay like this:

function Start()

    {Instantiate(characterSelected, transform.position, transform.rotation);}

My basic question is how do I say characterSelected=me and then pass characterSelected to following scenes.

Any help appreciated.
