I have an actionscript function that loads an external swf and is currently linked to a button in the same swf...

function btnClick(event:MouseEvent):void{
SoundMixer.stopAll();
 removeChild(loader); 
 loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onSWFLoaded);
 loader.load(movieSWF)
 loader.x=Xpos
 loader.y=Ypos
 addChild(loader)


}


button.addEventListener(MouseEvent.CLICK,btnClick);

I'm wondering if there is a way to call this function from a link on the page that the swf is housed on. I'm guessing javascript, php or swfaddress would be the most likely way, but I'm unbelievably new to all this so I'm not sure where to start or how to go about it.

Any help would be appreciated.
