I have created a bunch of page templates to use for

I have created a bunch of page templates to use for the tutorial section of my site, they use query_posts to grab posts of a particular category.
All works except for one thing, I have created a custom menu for navigating these pages but the buttons do not show active state, anybody got any ideas why this is ?

You can see here that i have used default pages with Marketpress shortcodes and that custom menu works fine
