Navigating trough my own loop

Hello there!

I’am having a big head ache with this.The thing is that I’ve been trying to create my own loop for a category page (You can see it in here) and when I finished all seemed perfect! Until I press “The next page” link. The structure gets all messed up!! Here you have my code, simplified:

<?php query_posts(‘showposts=2&cat=4′.’&paged=’.$paged); while(have_posts()) : the_post(); $do_not_duplicate[] = $post->ID;?>

<— The Post Structure —>

<?php endwhile; ?>
<?php query_posts(‘showposts=4&cat=4′.’&paged=’.$paged); while(have_posts()) : the_post(); $do_not_duplicate2[] = $post->ID;
if($post->ID == $do_not_duplicate[0] ||
$post->ID == $do_not_duplicate[1] ||
$post->ID == $do_not_duplicate[2]
) continue; update_post_caches($posts)?>

<— The Post Structure —>

<?php endwhile; ?>

<?php query_posts(‘showposts=6&cat=4′.’&paged=’.$paged); while(have_posts()) : the_post();
if($post->ID == $do_not_duplicate[0] ||
$post->ID == $do_not_duplicate[1] ||
$post->ID == $do_not_duplicate[2] ||
$post->ID == $do_not_duplicate2[0] ||
$post->ID == $do_not_duplicate2[1] ||
$post->ID == $do_not_duplicate2[2] ||
$post->ID == $do_not_duplicate2[3] ||
$post->ID == $do_not_duplicate2[4]
) continue; update_post_caches($posts);?>

<— The Post Structure —>

<?php endwhile; ?>

Any ideas? Enter to the link i put above and you’ll see what I want to get. Then click to go to the 2nd page, and you’ll see my problem.

Thank you!
