(37,42): error CS1525: Unexpected symbol `<', expecting `identifier'

i followed a tuturial on how to lock level in unity although i have a issue with one of the scripts and i just cant seam to figure out what is causing it an how to fix it
can someone please take a look and help resolve it?

using UnityEngine;
using System.Collections;
 
public class LevelSelectScript : MonoBehaviour {
 
 private int worldIndex;   
 private int levelIndex;   
 
 void  Start (){
  //loop thorugh all the worlds
  for(int i = 1; i <= LockLevel.worlds; i++){
   if(Application.loadedLevelName == "World"+i){
    worldIndex = i;
    CheckLockedLevels(); 
   }
  }
 }
 
 //Level to load on button click. Will be used for Level button click event 
 public void Selectlevel(string worldLevel){
  Application.LoadLevel("Level"+worldLevel); //load the level
 }
 
 //uncomment the below code if you have a main menu scene to navigate to it on clicking escape when in World1 scene
 /*public void  Update (){
  if (Input.GetKeyDown(KeyCode.Escape) ){
   Application.LoadLevel("MainMenu");
  }   
 }*/
  
 //function to check for the levels locked
 void  CheckLockedLevels (){
  //loop through the levels of a particular world
  for(int j = 1; j < LockLevel.levels; j++){
   levelIndex = (j+1);
   if((PlayerPrefs.GetInt("level"+worldIndex.ToString() +":" +levelIndex.ToString()))==1){
    GameObject.Find("LockedLevel"+(j+1)).<span id="IL_AD2" class="IL_AD">active</span> = false;
    Debug.Log ("Unlocked");
   }
  }
 }
}

GameObject.Find(“LockedLevel”+(j+1)).active = false;

What?
