Need script for a Close Window button

Sorry guys I just started Flash 3 weeks ago so I’m a Newbie!:sigh:

I made a button to load a .swf file on screen using this script:

on (release) { containerMC.loadMovie(“movieTest1.swf”);
}

Now I want to create a button in the movieTest1.swf file that will remove it from the screen. Basically its a close window button. Is this possible? What script do I assign to the button?
