Link Slider to Categories?

Hi,

There’s this post that helped me http://wordpress.org/support/topic/allow-front-page-page-link-to-allow-category-posts-to-be-displayed?replies=5

And this is what did:
In class-content-page.php :

After

<div class="entry-content">
            <?php the_content( __( 'Continue reading <span class="meta-nav">&rarr;</span>' , 'customizr' ) ); ?>

I added:

<?php $postid = get_the_ID();
				if ($postid == 787) $la_cat = 13;
				if ($postid == 1098) $la_cat = 5;
				if ($postid == 72) $la_cat = 1;
			 ?> 

            <?php query_posts('cat='.$la_cat.'&post_status=publish');?>
			<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
            <?php endwhile; else: endif; ?>

$postid numbers are the 3 posts that are on my front page (the circles)
and $la_cat is the category I want to show on each page.

Hope it helps!
