First Person Controller error, "IndexOutOfRangeException:Array index is out of range."

I'm using a default first person controller script combined with 2 javascript animation scripts, and I'm getting the titular error on line 172 of the aforementioned first person controller script. Here are the scripts I've been using. First Person Controller Script

Walking/Idle animation script

 #pragma strict
 
 function Start () {
 
 }
 
 function Update () {
    if (Input.GetAxis("Vertical") > 0.2)
        GetComponent.<Animation>().CrossFade ("Walking");
    else
       GetComponent.<Animation>().Play ("Idle");
 }
 

Jumping animation script

  #pragma strict
  
  var anim : Animation;
  
  function Start () {
      anim = gameObject.GetComponent("Animation");
  }
  
  function Update () {
       if (Input.GetButtonDown("Jump"))

I'd be really glad if anyone could help me out here.
