How to enable or disable a script OnTriggerEnter?

Ok, so I have been searching all over for help and right when I think I find a solution, I encounter a problem. I haven’t scripted in a bit, so I am a bit rusty. Anyways, I want to enable a script of a different GameObject (in this case, one on the Main Camera in the FPS player prefab) and I can’t seem to get it. Any time I try to use “.enabled” I get a syntax error. I have done this before, but cannot remember how. Here is what I have:
#pragma strict

function Start ()
{
	var Blur : GameObject.Find("First Person Controller");
	Blur.GetComponent("Indie Effects").enabled = false;
}

function OnTriggerEnter (col : Collider)
{
	if (col.tag == "Player")
	{
		Blur.active = true;
	}
}

function OnTriggerExit ()
{
	Blur.active = true;
}

Try this:

var Blur: GameObject; //The game object that has the script

Blur.GetComponent.<ScriptName>().enabled = false;
