CS8025 parsing error, can't find, halp !

 using UnityEngine;
 using System.Collections;
 
 public var cam1 : Camera;
 public var cam2 : Camera;
 
 function Update() {
     
 if (Input.GetKey(KeyCode.Enter))
     {
         cam1.camera.enabled = false;
         cam2.camera.enabled = true;
     }
 
 if (Input.GetKey(KeyCode.Spacebar))
     {
         cam1.camera.enabled = true;
         cam2.camera.enabled = false;
     }
 }

I'm a 3D graphic designer on an internship and I have a simple task to do, just switch between 2 cameras in a scene, nothing hard, but I've always been bad at coding, not that big of a deal since it's not my "job" at first, but I really can't find what's wrong in my code :/

It says "Assets/Scripts/camera_changing.cs(4,17): error CS8025: Parsing error"
