I’m trying to use lightbox from AS3, but I can’t make it to work…

The code I have is:

```auto

_contenedor.but.addEventListener(MouseEvent.CLICK,callJS);

function callJS(event:MouseEvent):void {
     ExternalInterface.call("PopFromFlash", "images/thumbs.jpg");
}

```

but it doesn’t work. The screen goes black and that’s it, it doesn’t show any picture. I already have added params.allowscriptaccess = “always”; in the swfobject…

And this is the js function that calls the lightbox, which it’s actually called because it popups the alert

\<script type=“text/javascript”\>  
function PopFromFlash(url) {  
var imgLink = document.createElement(‘a’);  
imgLink.setAttribute(‘href’, url);  
imgLink.setAttribute(‘rel’,‘lightbox’);  
Lightbox.prototype.start(imgLink);  
alert(“Test function”);

}  
\</script\>

Any help will be really appreciated. 😉
