i want my flashlight to do sound when turned on and off

Error: The name "audioSource" does not exist in current context

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Flashlight : MonoBehaviour
6. {
7.     public Light flashLight;
8.     public AudioSource AudioSource;
9.  
10.     public AudioClip soundFlashlightOn;
11.     public AudioClip soundFlashlightOff;
12.  
13.     private bool isActive;
14.  
15.     // Use this for initialization
16.     void Start ()
17.     {
18.         isActive = true;
19.     }
20.  
21.     // Update is called once per frame
22.     void Update()
23.     {
24.         if (Input.GetKeyDown(KeyCode.F))
25.         {
26.             if (isActive == false)
27.             {
28.                 flashLight.enabled = true;
29.                 isActive = true;
30.  
31.                 audioSource.PlayOneShot(soundFlashlightOn);
32.                  
33.             }
34.             else if (isActive == true)
35.             {
36.                 flashLight.enabled = false;
37.                 isActive = false;
38.  
39.                 audioSource.PlayOneShot(soundFlashlightOff);
40.             }
41.         }
42.     }
43. }
44.  

 

Capitalization must be 100% correct, just like spelling and punctuation.

 

Thanks ^-^
