Topic: One Gallery Works the others don't?????

Hi, bit of a newb but here goes, I have created a site which has a number of PostCard Viewer galleries linked to a news page, when I preview the site from dreamweaver all the links and galleries load and work fine, I have now uploaded the site to a server and only the graduation gallery link opens and loads, the rest simply give me a blank screen???

Any direction would be appreciated.

Cheers Sean
