Using strings to go to other scenes

Hi, I'm having a bit of a problem:

I'm trying to use an input text field as a cheat code input to move between 2 different scenes - if the code is correct, I want to go to one scene, but if the code is not correct, I want to go to a different scene. At the moment, no matter what I put into the text field, I end up going to the scene that's supposed to be for incorrect codes - even when I enter the correct code.

The code I'm using:

stop();

//stops on this scene

{

var cheat:String = "Enter Code Here";

//declaring a variable for a cheat code

_root.cheatBox.cheat = cheat;

//sets the text of the cheat box to cheat

_root.menuButton.onRelease = function()

//when the menu button is released

{

  gotoAndStop("Menu", 1);

  //goes to menu scene and stops on that scene

}

_root.cheatBox.goButton.onRelease = function()

//when the go button in the cheat box is released

{

  if(_root.cheatBox.cheat == "N0496151")

  //if the text box contains the code

  {

   gotoAndStop("Cheat", 1);

   //goes to the cheat scene and stops on that scene

  }

  else if(_root.cheatBoxcheat != "N0496151")

  //otherwise

  {

   gotoAndStop("Menu", 1);

   //goes to the menu scene and stops on that scene

  }

}

}

All of this code is on the main timeline, is there something I'm not doing right?
