how do I fix a parser error: unexpected symbol?

I was following one of the video tutorials for building a stealth game. In the c# script lastPlayerSighting I keep getting a parser error: unexpected symbol ‘panicAudio’ even though it’s been declared as a private audioSource.

using UnityEngine;
using System.Collections;

public class lastPlayerSighting : MonoBehaviour 
{
	public Vector3 position = new Vector3(1000f, 1000f, 1000f);
	public Vector3 resetPosition =  new Vector3(1000f, 1000f, 1000f);
	public float lightHightIntensity = .25f;
	public float lightlowIntensity = 0f;
	public float fadeSpeed = 7f;
	public float musicFadeSpeed = 1f;
	
	private alarmLight alarm;
	private Light mainLight;
	private AudioSource panicAudio;
	private AudioSource[] sirens;
	
	void awake()
	{
		alarm = GameObject.FindGameObjectWithTag(tags.alarm).GetComponent<alarmLight>();
		mainLight = GameObject.FindGameObjectWithTag(tags.mainLight).light
		panicAudio = transform.Find ("secondaryMusic").audio;
		GameObject[] sirenGameObjects = GameObject.FindGameObjectsWithTag(tags.siren);
		sirens = new AudioSource[sirenGameObjects.Length];
		
		for (int i = 0; i < sirens.Lenght; i++)
		{
			sirens _= sirenGameObjects*.audio;*_

* }*
* }*

* void update()*
* {*
* switchAlarms();*
* musicFading();*
* }*

* void switchAlarms()*
* {*
* alarm.alarmOn = (position != resetPosition);*

* float newIntensity;*

* if(position != resetPosition)*
* {*
* newIntensity = lightlowIntensity;*
* }*
* else*
* {*
* newIntensity = lightHightIntensity;*
* }*

_ mainLight.intensity = Mathf.Lerp(mainLight.intensity, newIntensity, fadeSpeed * Time.deltaTime);_

* for(int i = 0; i < sirens.Length; i++)*
* {*
_ if(position != resetPosition && !sirens*.isPlaying)
{
sirens.Play();
}
else if(position == resetPosition)
{
sirens.Stop ();
}
}
}*_

* void musicFading()*
* {*
* if(position != resetPosition)*
* {*
_ audio.volume = Mathf.Lerp(audio.volume, 0f, musicFadeSpeed * Time.deltaTime);
panicAudio.volume = Mathf.Lerp(panicAudio.volume, 0.8f, musicFadeSpeed * Time.deltaTime);
* }
else*

* {
audio.volume = Mathf.Lerp(audio.volume, 0.8f, musicFadeSpeed * Time.deltaTime);
panicAudio.volume = Mathf.Lerp(panicAudio.volume, 0f, musicFadeSpeed * Time.deltaTime);
}
}*_

}

Missing semicolon at the end of this line:

mainLight = GameObject.FindGameObjectWithTag(tags.mainLight).light
