Executing Actions Through PlayerPrefs

Hey, I’m working on a game that has an “options” scene where players can change the options. I have only coded my first option: the Audio, but it doesn’t seem to be working. What I want it to do is change a playerpref value when a button is clicked on, and then use that value to do different things:
I have two scripts for the buttons being pressed:

#pragma strict

function OnMouseUp () 
{

	PlayerPrefs.SetInt("Audio", 0);

}

and I also have:

#pragma strict

function OnMouseUp () 
{

	PlayerPrefs.SetInt("Audio", 1);

}

The script that executes the action is :

function Update () 
{
PlayerPrefs.GetInt("Audio");

	if Audio== 1
	{

	GameObject.Find("audioon").GetComponent(SpriteRenderer).enabled = false;

	GameObject.Find("audioon1").GetComponent(SpriteRenderer).enabled = true;

	GameObject.Find("audiooff").GetComponent(SpriteRenderer).enabled = true;

	GameObject.Find("audiooff1").GetComponent(SpriteRenderer).enabled = false;

	AudioListener.volume = 1;

	}

	if Audio==0
	{

	GameObject.Find("audioon").GetComponent(SpriteRenderer).enabled = true;

	GameObject.Find("audioon1").GetComponent(SpriteRenderer).enabled = false;

	GameObject.Find("audiooff").GetComponent(SpriteRenderer).enabled = false;

	GameObject.Find("audiooff1").GetComponent(SpriteRenderer).enabled = true;

	AudioListener.volume = 0;
	}
			
}

Actually I fixed this a few days ago, I don’t need help anymore.
