WooCommerce ADD TO CART Issue

I am currently having an issue making the “add to cart” button show up as well…

http://173.254.53.244/~cottage/shop/bindings-skis/radar-vector-boot-2013/

I added the `function mv_my_theme_scripts()
{
wp_enqueue_script(‘add-to-cart-variation’, plugins_url() . ‘/woocommerce/assets/js/frontend/add-to-cart-variation.js’,array(‘jquery’),’1.0′,true);
}
add_action(‘wp_enqueue_scripts’,’mv_my_theme_scripts’);`

to my functions.php file and the <script type=’text/javascript’ src=’http://my-site.com/wp-content/plugins/woocommerce/assets/js/frontend/add-to-cart-variation.min.js?ver=1.6.5.2′></script&gt;
to my head.php (i also added the folders assets/js/frontend to my theme with the JS in it as well…

im not having a good experience with this, could someone please help me?

NOTE: I am using ‘theretailer’ as a theme
