Calling individual variables from individual scripts

In the Inspector each script has a different pair of values for Note1aTexture and Note1bTexture but in-game I can only ever pull up one texture – no matter how specific I am about referring to this script that’s being run from the object that just collided with the player. What am I doing wrong or failing to comprehend?

private var hasCollided: boolean = false;
private var usedState: boolean = false;
var labelText: String = "";
var Note1aTexture: Texture;
var Note1bTexture: Texture;
var pickupSound: AudioClip;
var pgWidth = Screen.width/2;
var pgHeight = Screen.height/1.5;
var pgW2 = pgWidth/2;
var pgH2 = pgHeight/2;
var pgX = 0;
var pgY = 0;
var pgMargin = 32;


function Update(){
	if (hasCollided == true){
		if (Input.GetKeyDown(KeyCode.E)){
			if (this.usedState == true){
					Destroy( transform.root.gameObject );
			}
				
			if (this.usedState == false){
				this.usedState = true;
				print("Player picked up item.");
				audio.PlayOneShot(pickupSound);
				if (tag == "Note"){
					print("It was a note.");
				}
			}
		}
	}
}
 
function OnGUI()
    {
    if (usedState == true){
    	GUI.DrawTexture(Rect(pgX,pgY,pgWidth,pgHeight),this.Note1aTexture,ScaleMode.StretchToFill,true,0.0f);    	
    	GUI.DrawTexture(Rect(pgX+pgMargin*2,pgY+pgMargin,pgWidth-pgMargin*8,pgHeight-pgMargin),this.Note1bTexture,ScaleMode.StretchToFill,true,0.0f);
    	GUI.Box(Rect(140,Screen.height-50,Screen.width-300,120),("Press E to add to Journal; Space to put it down."));
    	
		if (Input.GetKeyDown(KeyCode.Space)){
    		this.usedState = false;
    		audio.PlayOneShot(pickupSound);
    	}    	
    }
    if (this.usedState == false){
       if (this.hasCollided ==true){  
      		GUI.Box(Rect(140,Screen.height/2,Screen.width-300,32),(labelText));
    	}
    }    
}
 
function OnTriggerEnter(c:Collider){
    if(c.gameObject.tag =="Player"){
    	this.GetComponent.<PickUpNote1>().hasCollided = true;
	}
}
 
function OnTriggerExit( other : Collider ){
	this.GetComponent.<PickUpNote1>().hasCollided = false;
}

This is JS? In C# when you say this.var or this.method you are saying basically “my instance, the one I am executing right now”. What texture are you trying to get? Are you trying to grab a texture stored on a script in the item you are picking up?
