WC Storefront declaration

Hi,

Could you explain why the below woocommerce.php script does’t work?
Thanks
————————————————————————-
<?php

get_header(); ?>
<div id=”primary” class=”content-area”>
<main id=”main” class=”site-main” role=”main”>

<?php woocommerce_content(); ?>

</main><!– #main –>
</div><!– #primary –>

<?php do_action( ‘storefront_sidebar’ ); ?>
<?php get_footer(); ?>
