Page templates

Hi, I’m trying to make a full width content page but can’t seem to create a template that works with this team simply making a duplicate page.php width different name and template name it. WordPress admin won’t find it when creating a new page.

Any ideas of why?

<?php
/*
Template Name: Full Width
*/

get_header(); ?>

	<div id="primary" class="content-area clearfix">
		<div id="content" style="width:100%">

			<?php while ( have_posts() ) : the_post(); ?>

				<?php get_template_part( 'content', 'page' ); ?>

				<?php
					// If comments are open or we have at least one comment, load up the comment template
					if ( comments_open() || '0' != get_comments_number() )
						comments_template();
				?>

			<?php endwhile; // end of the loop. ?>

		</div><!-- #content -->
	</div><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>
