Topic: Lightbox for read more pop up ?

Hey, have been looking for a simple but highly customisable script for a while now and have set this up how I want it except 1 thing is not working and 1 thing I want to know how to make possible?  I need my news stories to appear in a pop up box, when I do this using this story as an example it tries to access: print.php?id=1&popup=news and feeds the following error: ID not found for active news. So if this problem if easily fixable how can I make it load in a lightbox? I know how to set up lightbox scripts just need to know how I can call it using the pop up feature? Any help would be great?

Thanks

Ben
