[HELP]Get Page[/HELP]

[Oui]

Okay Im Using

PHP Code:
switch($_GET['page']){
    case home:
        include("includes/home.php");
    break;
    case forum:
        include("includes/forum.php");
    break;
    case maintenace:
        include("includes/maintenace.php");
    break;
    //Etc
}

That Code.
It Just Includes The Second Mage
And I Just Want One Page To Show At A Time.
How Would That Work?
