title: Wordpress page navigation within posts
body: <p>I have a page template in wordpress that only shows posts from a specific category with ID 972. I've limited it so that it displays 8 posts on the page. I was wondering if it would be possible to display page navigation at the bottom, so that I could go to the next post page <strong>ONLY</strong> from the posts with category ID 972. Is this possible?</p>
  
  <p>EDIT:
  the <code>post_nav_link();</code> function doesn't work for me...</p>
  
  <p>Thanks!
  Amit</p>
