Left and Right Sidebars

I have attempted to create a sidebar-left.php and a sidebar-right.php file in the theme and changed the the index.php the use these files as follows.

<?php
/**
 * The main template file.
 *
 * This is the most generic template file in a WordPress theme
 * and one of the two required files for a theme (the other being style.css).
 * It is used to display a page when nothing more specific matches a query.
 * E.g., it puts together the home page when no home.php file exists.
 * Learn more: http://codex.wordpress.org/Template_Hierarchy
 *
 * @package Quark
 * @since Quark 1.0
 */

get_header(); ?>

	<div id="primary" class="site-content row" role="main">

		<?php get_sidebar-left(); ?>
		<div class="col grid_8_of_12">

			<?php if ( have_posts() ) : ?>

				<?php // Start the Loop ?>
				<?php while ( have_posts() ) : the_post(); ?>
					<?php get_template_part( 'content', get_post_format() ); // Include the Post-Format-specific template for the content ?>
				<?php endwhile; ?>

				<?php quark_content_nav( 'nav-below' ); ?>

			<?php else : ?>

				<?php get_template_part( 'no-results' ); // Include the template that displays a message that posts cannot be found ?>

			<?php endif; // end have_posts() check ?>

		</div> <!-- /.col.grid_8_of_12 -->
		<?php get_sidebar-right(); ?>

	</div> <!-- /#primary.site-content.row -->

<?php get_footer(); ?>

I have also changed the functions.php to include registration of those two sidebar widget areas. When I view the homepage of the sight I only get the content area. I am in production mode so do not have the site online yet. I am not sure what I am doing wrong. Tell me what you need to help you see what I might have missed.

Thanks
