If statement in Archive.php

Hi Folks,
I’ve got a small issue with my archive.php. I was trying to set up an If statement that displays a certain category and sub categories with a different layout & sidebar based on my theme options. I’ve placed a small bit of code in the start of my archive.php in order to set these options based on if the post is in category ‘nytt’ or is a sub cat of nyytt (ID 49). It works like a charm, if the category listing in part of NYTT or a sub cat, but now, all other categories don’t display, the page won’t load further than the header. And for the life of me I can’t figure out why. I’m staring at this code like it holds a secret which it won’t give up..

<?php
get_header();

$subtitle=get_opt("_posts_subtitle");
$slider='none';
if ( in_category( 'nytt' ) || post_is_in_descendant_category( 49 ) ) {
	$layout='left';
	$sidebar ='teacher-training';
}
else {
	$layout = get_opt('_blog_layout');
	$sidebar = get_opt('_blog_sidebar');
}

include(TEMPLATEPATH . '/includes/page-header.php');

?>

<div id="content-container" class="content-gradient <?php echo $layoutclass; ?> ">
<div id="<?php echo $content_id; ?>"><?php

if(have_posts()){
	while(have_posts()){
		the_post();
		global $more;
		$more = 0;

	include(TEMPLATEPATH . '/includes/post-template.php');	

	} 

	print_pagination(); 

}else{
	echo ('No posts available');
}

?>
</div>
<?php
if($layout!='full'){
	 print_sidebar($sidebar);
}
?>

<div class="clear"></div>
</div>
<?php
get_footer();
?>

Any help would be awesome. Thanks for your time!
