Flash, XML and troubles

1

I’ve run into a strange thing that I cannot seem to find the answer to.

I have a basic slider of thumbnails that goes horizontally. The thumbnails are then labeled and linked to a pop up containing the larger version of the image using an XML file. The XML code goes like this:

<proj>
		<label>Artwork - Angel Cell</label>
		<link>/art02.htm</link>
		<width>600</width>
		<height>400</height>
		<pic>artwork02.jpg</pic>
</proj>

As an addition, here’s the actionscript that calls the new window:

function launchProject(_arg1) {
	myURL = new String(("'popup"+_arg1.launchURL)+"'");
	myHeight = new String(("'height="+_arg1.launchHeight)+",");
	myWidth = new String(("width="+_arg1.launchWidth)+",");
	getURL((((("javascript:openNewWindow("+myURL)+",'HMX',")+myHeight)+myWidth)+"toolbar=no,scrollbars=no')");

When I open the HTML page with the Flash file embeded in it, everything functions fine and as it should. But when I then place the HTML file in an iframe on the main page, the links do not pop up. The label appears as I’ve told it to and the slider functions fine.

Any thoughts on this?
