FlvPlayback Skin Custom Button calling external function

[ssystems]

Hi Guys,

I have a movie clip on a flvplayback skin. On the mouse click of that movie clip I need to fire a JS that is on the page (not on the AS). I am able to fire the calling event and reach the AS. However, I am not able to reach the JS side.

my_object.addEventListener(MouseEvent.CLICK, externalFunction);
 
function externalFunction(){
    ExternalInterface.call("ExternalFunction");
}

All I need is to call the "ExternalFunction". Any help would be highly appreciated.
