Audio Clip Trigger

Hi,

Could someone help me out with the script below? Can't quite see why this isn't working.

If i comment out the else statement it works, but the wrong way round. Once i let go of the 'vertical' button the audio plays and then stops once i click it again. I want it the other way round, but it should already be doing that...

Any ideas?

Thanks

Code (JavaScript):

1.  
2. var forestAudio : AudioClip;
3. var enteredArea : boolean = false;
4.  
5. function Update (){
6. var Audio = gameObject.GetComponent(AudioSource);
7. Audio.clip = forestAudio;
8.     if(Input.GetButton("Vertical") && enteredArea == true)
9.      {
10.       Audio.Play();
11.      }
12.      else
13.       {
14.        Audio.Pause();
15.       }
16. }
17.  
18. function OnTriggerEnter (col : Collider)
19. {
20.         if(col.gameObject.name == "GrassSound")
21.           {
22.              enteredArea = true;          
23.           }    
24. }
