Javascript Movement Script. Why am I getting these errors?

Hey,

I am currently working on a input/movement script for a simple top-down 2D RPG using javascript.

Here is what I have written so far:

 #pragma strict
 
     /* ========== Define Variables ========== */
 
 var moveSpeed : float = 10.0;
 var playerSprite : PackedSprite;
 
 
 
 
 function Update () {
 
 var thisTransform : Transform;
 var moving : boolean;
 
 var movingLeft : boolean = false;
 var movingRight : boolean = false;
 var movingUp : boolean = false;
 var movingDown : boolean = false;
 
 var wasMovingLeft : boolean;
 var wasMovingRight : boolean;
 var wasMovingUp : boolean;
 var wasMovingDown : boolean;
 
 var movement : float;
 var horMoveDir : int;
 var verMoveDir : int;
 
 
 thisTransform = transform;
 
     /* ========== Keyboard Input ==========*/
 
     if(Input.GetKey("left")) {
         horMoveDir = -1;
         verMoveDir = 0;
         wasMovingLeft = true;
         wasMovingRight = false;
         wasMovingUp = false;
         wasMovingDown = false;
     
         
         if(!movingLeft) {
             movingLeft = true;
             movingRight = false;
             movingUp = false;
             movingDown = false;
             AnimateWalk();
         }
     }
         
     if(Input.GetKey("right")) {
         horMoveDir = 1;
         verMoveDir = 0;
         wasMovingLeft = false;
         wasMovingRight = true;
         wasMovingUp = false;
         wasMovingDown = false;
     
         
         if(!movingRight) {
             movingLeft = false;
             movingRight = true;
             movingUp = false;
             movingDown = false;
             AnimateWalk();
         }
     }
         
     if(Input.GetKey("up")) {
         horMoveDir = 0;
         verMoveDir = 1;
         wasMovingLeft = false;
         wasMovingRight = false;
         wasMovingUp = true;
         wasMovingDown = false;
 
         
         if(!movingUp) {
             movingLeft = false;
             movingRight = false;
             movingUp = true;
             movingDown = false;
             AnimateWalk();
         }
     }
         
     if(Input.GetKey("down")) {
         horMoveDir = 0;
         verMoveDir = -1;
         wasMovingLeft = false;
         wasMovingRight = false;
         wasMovingUp = false;
         wasMovingDown = true;
         
 
         
         if(!movingDown) {
             movingLeft = false;
             movingRight = false;
             movingUp = false;
             movingDown = true;
             AnimateWalk();
         }
     }
 
         
     /* ========== Animate Walk ==========*/
         
     function AnimateWalk() {
         if(movingLeft) {
             playerSprite.PlayAnim(3);
         }
         
         if(movingRight) {    /*Try "else if" if this doesn't work*/
             playerSprite.PlayAnim(2);
         }
         
         if(movingUp) {
             playerSprite.PlayAnim(0);
         }
         
         if(movingDown) {
             playerSprite.PlayAnim(1);
         }
     }
     
 }

The Unity Console is returning the following errors for it:

 (111,18): BCE0044: expecting (, found 'AnimateWalk'.
 (111,31): UCE0001: ';' expected. Insert semicolon at the end.
 (112,17): BCE0043: Unexpected token: if.
 (112,31): UCE0001: ';' expected. Insert a semicolon at the end.
 (113,49): BCE0044: expecting :, found ';'.

(line 111 is the first after "Animate Walk" comment)

I have no idea why. These characters obviously shouldn't be where it says they should. (should they? :S).

I am very new to Unityscript and I get the feeling I'm missing something ridiculously obvious, but I've spent most of the day trying to figure this out and it's baffling me. Anybody lend a hand?
