You'd need to do an inline content lightbox by adding an id onto your div like this (just add this on the same page as your link in the text editor)
<script type="text/javascript" src="http://Myserver.com/blah.js"></script> <div id="lightbox-content" style="width:600px; height:500px;"> <object width="600" height="500" style="display:none;"> <param name="host_url" value="http://Myserver.com" /> <param name="name" value="ABC/XYZ"/> </object> </div>
And then using a link like this:
<a href="#lightbox-content"> link </a>
Your could also hide the initial div from displaying outside of the lightbox with css
#lightbox-content { display: none; }
Cheers
