GameObject, Select Parent As Object

Hello all, I am trying to create a segment of hallway that when the player passes through a plane it renders, and when the player passes through the second plane it is destroyed. I am able to use the GameObject to select the parent hallway for the second plane with no problem, however I can not select the parent for the first plane. I would appreciate any help or explanation as why this is the case.

Plane 1- Render Hallway (Can only select 1 object, parent renders before trigger)

var hall : GameObject; var played = false; var trig = false;

function Start () { trig = false; hall.GetComponent.().enabled = false; }

function OnTriggerEnter (other : Collider) { trig = true; }

 function Update () {
     if (trig == true) {
         hall.GetComponent.<Renderer>().enabled = true;
               }
     else {
         hall.GetComponent.<Renderer>().enabled = false;
     }
         
 }
   

Plane 2- Destroy Hallway (Can select parent as GameObject)

var hall : GameObject; var played = false; var trig = false;

function Start () { trig = false; hall.GetComponent.().enabled = false; }

function OnTriggerEnter (other : Collider) { trig = true; }

 function Update () {
     if (trig == true) {
         Destroy(this.gameObject);
         Destroy(hall.gameObject);
     }
 }

Thank you all in advance, Respectfully, Gabriel
