Need help fixing my script

Im trying to disable a script and play animation when coliding with an object with a tag.

#pragma strict

public var gameObject : GameObject;

function Update () {
}

function OnTriggerEnter (col : Collider) {
    if(col.gameObject.tag == "Weapon") {
    GameObject.GetComponent(Chase).enabled = false;
        GetComponent.<Animation>().Play();

    }
}

I guess you want to replace

GameObject.GetComponent(Chase).enabled = false;

with

gameObject.GetComponent(Chase).enabled = false;
