Load fancybox page through "Facebox image and content viewer"(or other alternatives)

Question

Hi, I'm trying to load a different fancybox page every time someone clicks one of the links on the left menu.

example: http://cupones.com.ec/stackoverflow/

I am using the Facebox image and content viewer plugin. The first link "pizzerias" loads an image with no problem. However there is a problem displaying the second "mexicanos" link to an html page that uses fancybox and looks exactly like this: http://cupones.com.ec/fancybox/cupones-beta.html

Can anyone think of a solution/workaround or perhaps a different way to dynamically load fancybox html pages when clicking on the menu links.

Thanks in advance :)
