category page

I created a category page and named it category-3.php

The pages code is below:

<?php get_header(); ?> <!-- header include -->

	<div id="left">
		<div id="left-top">
			<h2>Product Catalog</h2>
		</div><!-- end left-top -->	

		<div class="blog-content">
			<?php query_posts('cat=3&showposts=3'); ?>
			<?php if(have_posts()) : ?><?php while(have_posts()) : the_post(); ?>
			<h2><?php the_title(); ?></h2>
			<p>
				<?php the_content(); ?>
			</p>

			<?php endwhile; ?>
		</div><!-- end blog-content -->		

		<div id="catalog-pages">
			<p>
				<?php posts_nav_link('<span style="padding-left: 50px"></span>','Previous','Next'); ?>
			</p>
		</div><!-- end catalog-page numbers -->

	</div><!-- end left -->

<?php get_sidebar(); ?> <!-- sidebar include -->

<?php get_footer(); ?> <!-- footer include -->

</div> <!-- wrap end -->
</body>
</html>

I uploaded this into my theme folder and when i direct my browser to the page, it get “Nothing Here” and the content doesn’t show.

What am I doing wrong?

Thanks in advance!
