query posts – post_type array

Hi,

I have a query with an array containing all post_types. This sort of works fine although the final part of my query after the array doesn’t seem to work, it should only show category 13 and 5 posts

my site: here

<?php query_posts(array(
	        'post_type' => array(
	                    'post',
	                    'page',
	                    'our-work',
	                    'careers',
						'blog',
						'news'
	                ),'&cat=13&showposts=5')); ?>
