IndexOutOfRangeExeption - Array index is out of range

Hello,

Does anyone know how to fix the error, I just can't figure it out and nobody else has encountered this error in combination with something like my script.

Here's the error: IndexOutOfRangeExeption: Array index is out of range. ScanConsole.Update () (at Assets/Scripts/ScanConsole.js:19)

And here's the script:

 public var computer : GameObject;
 public var textMesh : TextMesh;
 public var cam : GameObject;
 public var scanGui : GameObject;
 public var index : int = 0;
 
 public var inScanner : GameObject[] = new GameObject[1];
     
 public var isExit : boolean = false;
 public var isArrayDisplay : boolean = false;
 
 function Start () {
     textMesh = GetComponent(TextMesh);
 }
 
 //textMesh.text = "";
 
 function Update () {
     textMesh.text = "Selected: " +
     inScanner[index].transform.name;
 }
 
 function OnMouseDown () {
     if(isExit){
         cam.SendMessage("ExitGUI",
          SendMessageOptions.DontRequireReceiver);
     }
 }

Thanks!
