theme only shows products on template file page.php

Hello,

I have a custom theme I’m developing. Everything works fine when Marketpress is writing to the page.php template file. When I copy page.php and rename it “mp_global_category.php” no content is displayed?? Is there something I need to add into my copied and renamed page.php file? Using TwentyEleven as the base for my custom theme.

Thanks!
