Elevator script gives compiler errors. help!

So I am making this elevator script and it all goes well. Both of the functions worked properly before, just separate. Heres the code:

 public var elevatorSpeed : float = 3.0;
 public var Character : GameObject;
 var characterIn : boolean = false;
 
 function Update () 
 {
     if(characterIn == true){
         if(Input.GetKey (KeyCode.R)) {
         transform.Translate(Vector3.down * elevatorSpeed * Time.deltaTime);
         }
         
         if(Input.GetKey (KeyCode.E)) {
         transform.Translate(Vector3.up * elevatorSpeed * Time.deltaTime);
     }
 }
 
 function OnTriggerEnter(other : Collider)
 {
     Debug.Log("Character Entered", Character);
     characterIn = true;
 }
