Parsing error CS8025

Need to add a script so that a character in my project talks when a user clicks on it. Unity is saying I have a parsing error CS8025. here is my script

using UnityEngine; using System.Collections;

public class HannahVoice : MonoBehaviour {

 // Use this for initialization
 void Start () {
 
 }
 
 // Update is called once per frame
 void Update () {
 
 }

}

var papers : int = 0; var papersToWin = 5; var distanceToPaper : float = 2.5; public var paperPickup : AudioClip;

function Start () {

 Screen.lockCursor = true;

}

function Update () { if(Input.GetMouseButtonDown (0) || Input.GetKeyDown (KeyCode.E)) { var ray = Camera.main.ScreenPointToRay(Vector3(Screen.width 0.5, Screen.height 0.5, 0.0)); var hit : RaycastHit;

 if(Physics.Raycast(ray, hit, distanceToPaper))
 {
 if(hit.collider.gameObject.name == “Casual_08___Stand”)
 {
  papers += 1;
  GetComponent.<AudioSource>().PlayClipAtPoint(paperPickup, transform.position);
 }
 }
 }

}

I am very new to this, any help is vastly appreciated

 using UnityEngine;
 
 public class HannahVoice : $$anonymous$$onoBehaviour {
 //your code
 }
