Creating HTML Links in AS3

Hi

I have this example here:
http://www.qwertypcs.co.uk/as3test2.html

This is using Thickbox, and this the code I am using in Flash:


eg1Mc.addEventListener(MouseEvent.CLICK, onClick);



import flash.external.ExternalInterface;

function onClick(event:MouseEvent):void
{
	 ExternalInterface.call("tb_show" , "Elizabeth Martin Website" , "images/slidec.jpg?cid=6&height=450&width=560" , false);
}


eg1Mc.buttonMode = true;

Where I have Elizabeth Martin Website as a caption how would I change this so I could have:

Elizabeth Martin Website
Click to see this site

Where click to see would obviously be a link to the site?

Can this be done in AS3 or would it be done via the javascript file that this code calls?
