Trouble making the Main Menu "Start" button work

Unity Engine
1

The Main Menu is a scene, named “Main Menu”. I want to load the next scene, called “Game”. The Main Menu has 2 components: an image and the “Start” text. To the text, I attached this script:

public class Start_Script : MonoBehaviour {
    void OnMouseEnter()
    {
        Application.LoadLevel ("Game");
    }
}

But when I click it, it doesn’t work. How to solve it?

Does you GameObject have a collider? OnMouseDown is only called on objects with a collider.

These days you are probably better off using the event system interfaces anyway.
