Assets/PlayerControl.js(3,21): UCE0001: ';' expected. Insert a semicolon at the end.

Why isnt it working, I can't add player movement in unity!!!1

 #pragma strict

 var moveUp : KeyCode
 var moveDown : KeyCode

 var speed : float = 10;

     function Update ()
     {
     if (Input.GetKey(moveUp))
     {
             
     }
     else if (Input.GetKey(moveDown))
     {
         
     }
     else
     {
         
     }
 }
