etstinson on "Woocomerce adding single product info to category page"

I'm trying to highlight a single product at the top of my category page. I've added this code, which I just took from the content-single-product.php, to the archive-product.php file.

<?php
    	  global $product;

				/**
				 * woocommerce_before_single_product hook
				 *
				 * @hooked woocommerce_show_messages - 10
				 */
				 do_action( 'woocommerce_before_single_product' );
			?>

			<!-- BEGIN .main-item -->
			<section <?php post_class('main-item clearfix'); ?>>

			<?php
				/**
				 * woocommerce_show_product_images hook
				 *
				 * @hooked woocommerce_show_product_sale_flash - 10
				 * @hooked woocommerce_show_product_images - 20
				 */
				do_action( 'woocommerce_before_single_product_summary' );
			?>

			<div class="item-info">
        <h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
        <div class="item-text">
          <?php  echo apply_filters( 'woocommerce_short_description', $post->post_excerpt ) ?>
        </div>
       	<?php
          if($product->product_type != 'external')
          {
            //get form opening
            $params = array();

            if($product->product_type == 'variable')
            {
              $params = array( 'available_variations'  => $product->get_available_variations() );
            }

            woocommerce_get_template('single-product/form.php', $params);
          }
       	?>
      <div class="details clearfix">

        <?php
          //if product is variable type, show variants
          if($product->product_type == 'variable')
          {
            woocommerce_get_template( 'single-product/variants.php', array(
                                      'available_variations'  => $product->get_available_variations(),

                              			  'selected_attributes' 	=> $product->get_variation_default_attributes()
                          		      ) );
           }
         ?>

         <?php
			     if ( ! $product->is_sold_individually() && $product->product_type != 'external' &&
                $product->product_type != 'grouped')
	 			   {
             woocommerce_quantity_input( array( 'min_value' => apply_filters(
                                         'woocommerce_quantity_input_min', 1, $product ),
                              				   'max_value' => apply_filters( 'woocommerce_quantity_input_max',
                                          $product->backorders_allowed() ? '' :

                          			               )
                    		  	            );
            }
          ?>

          <?php woocommerce_template_single_meta(); ?>

          <?php woocommerce_template_single_sharing(); ?>

It works great when I view the store page, but when I go to a category page the description doesn't show up.

I would really appreciate some help.

Here's a link to the problematic page: Category
