Main Menu Script Issues

I’m coding a game based off the book Maze Runner, and so I created 2 levels named MazeRunner and Main Menu. The MazeRunner Level is working smoothly, but the main menu is having issues with the script. It’s saying MissingMethodException:UnityEngine.Application.LoadLevelName. Can anyone help me? This is for a project that is due this Friday! Here is my script

var quit=false;

function OnMouseEnter()
{

renderer.material.color = Color.green;		//Change Color to green!

}

function OnMouseExit()
{

renderer.material.color = Color.white;		//Change Color to white!

}

function OnMouseUp()
{

if (quit == true)
{
	Application.Quit();					    //If you click on quit aplication quits.
}
else
{
	Application.LoadLevelName ("Maze Runner");				//If you click on other button it loads game!
}

}

function Update()
{
if (Input.GetKey(KeyCode.Escape)) //If you press (escape) game force closes!
{
Application.Quit();
}

}

What exactly is Application.LoadLevelName in your code? There is no such variable/method in Unity’s Application class. Closest I see is Application.loadedLevelName.

To actually load a different scene, it’s Application.LoadLevel (and a couple similar ones).
