error CS8025 (Parsing Error)

this is my code… can somebody tell me what’s wrong?
using UnityEngine;
using System.Collections;

public class Parallaxing : MonoBehaviour {

public Transform[] backgrounds;         //Array (list) of all the back- and foregrounds to be parallaxed
private float[] parallaxScales;         //The proportion of the camera's movement to move the backgrounds by
public float smoothing = 1f;                // How smooth the parallax is going to be. Make sure to set this above 0.

private Transform cam;                 //reference to the main cameras transform
private Vector3 previousCamPos;        //The position of the camera in the previous frame

//Is called before Start(). Great for references.
void Awake () {
	//set up camera reference
	cam = Camera.main.transform;}

// Use this for initialization
void Start () {
    // The previous frame had the current frame's camera position
	previousCamPos = cam.position;

	//assigning coresponding parallaxScales
	parallaxScales = new float[backgrounds.Length];
	for (int i = 0; i < backgrounds.Length; i++) {
		parallaxScales <em>= backgrounds_.position.z*-1;_</em>

* }*
* }*

* // Update is called once per frame*
* void Update () {*

* //for each background*
* for (int i = 0; i < backgrounds.Length; i++) {*
* //the parallax is the opposite of the camera movement because the previous frame multiplied by the scale*
_ float parallax = (previousCamPos.x - cam.position.x) * parallaxScales*;
// set a target x position which is the current position plus the parallax*
float backgroundTargetPosX = backgrounds*.position.x + parallax;

Vector3 backgroundTargetPos = new Vector3 (backgroundTargetPosX, backgrounds.position.y, backgrounds.position.z);

You’re just missing a closing brace on the last line.
