Pausing external swf

1

This code loads an external intro movie, and allows me to remove it when I hit the back button. I was wondering how I can add another button that pauses/plays the introPage.swf at whim from the container .swf file?


function init() {
    holder.loadMovie("introPage.swf")
    intro_btn._visible = false;
}
init();

home_btn.onRelease = function() {
    holder.unloadMovie("introPage.swf")
    intro_btn._visible = true;

};
