Displaying 2 different category posts on outside WordPress page

So I am trying to get two different categories to display on my homepage. The blog is located in the /results/ folder. And on the home page I want to display two categories in different sections. One is a “portfolio” category and the other is a “news” category. I can easily display one category, but it gets tricky when I try displaying the second category.

Here is the code I used for the first category:

<?php
define('WP_USE_THEMES', false);
require('results/wp-blog-header.php'); ?>

<?
 if (is_home()) {

	  query_posts('showposts=1&amp;order=desc&amp;cat=18');
   }

if (have_posts()) :
   while (have_posts()) :
      the_post();
	  ?><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>" id="resultspage"><?php the_title(); ?></a><?
	  the_content();
   endwhile;
endif;
?>

I think it’s pretty straight forward.

Now later on in the code I want to display the “news” category. So I do the following:

<?

 if (is_home()) {

	  query_posts('showposts=2&amp;order=desc&amp;cat=21');
   }

  if (have_posts()) :
   while (have_posts()) :
      the_post();
	  ?><li><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>">
<?php the_title(); ?></a></li><?
   endwhile;
endif;

   ?>

It still display the first category’s post (18) and not the new category. What am I doing wrong? Is this possible?
