Lost my template selector

I have in some way lost my template selector, so when I write a new page I cant select a template ??
I use 3 sidebars, do you think that can be the problem?

I have add this line to my functions.php in my theme lib.
<?php if ( function_exists('register_sidebars') ) register_sidebar('1'); register_sidebar('2'); register_sidebar('3');?>

This is my sidebar code:

<!-- begin sidebar -->

<div id="sidebar">
<?php echo ddlsp_generate(); ?>

	<ul id="sidebarwidgeted">

	<?php if ( function_exists('dynamic_sidebar') && dynamic_sidebar(1) ) : else : ?>

	<?php endif; ?>

	</ul>

</div>

<!-- end sidebar -->

This is my page code:

<?php get_header(); ?>

<div id="content">

	<div id="contentleft">

		<div class="postarea">

			<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
			<h1><?php the_title(); ?></h1>

			<?php the_content(__('[L&aelig;s mere]'));?>

			<?php endwhile; else: ?>

			<?php _e('Sorry, no posts matched your criteria.'); ?>
<?php endif; ?>

		</div>

	</div>

<?php include(TEMPLATEPATH."/sidebar_page.php");?>

</div>

<!-- The main column ends  -->

<?php get_footer(); ?>
