Previous / Next Entries links not working

Hi everybody,

I’m having an issue with this page:

http://msgjustice.com/results/

The Previous / Next Entries links at the bottom of the page are not working (per se). The address bar in the browser will say you are on page2 but it will show the same first 6 of the 8 posts in the category.

I presume this is because I’m using:

<?php
query_posts('posts_per_page=6&cat=425');
if ( have_posts() ) : while ( have_posts() ) : the_post();
?>

The intent here is to have a page that shows just post titles from one category. The rest of the code for the template is very standard.

Thanks for any info.
