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;
 }
