in the code

[code] /* case 'PRODUCT_LIST_BUY_NOW':
            $lc_align = 'center';
            $lc_text = '<a href="' . tep_href_link(basename($PHP_SELF), tep_get_all_get_params(array('action')) . 'action=buy_now&products_id=' . $listing['products_id']) . '">' . tep_image_button('button_buy_now.gif', TEXT_BUY . $listing['products_name'] . TEXT_NOW) . '</a>&nbsp;';
            break;
        } */

         case 'PRODUCT_LIST_BUY_NOW': 
         $lc_align = 'center'; 
         if (tep_get_products_stock($listing_values['products_id'])> 0) 
         { 
         $lc_text = '<a href="' . tep_href_link(basename($PHP_SELF), tep_get_all_get_params(array('action')) . 'action=buy_now&products_id=' . $listing_values['products_id'], 'NONSSL') . '">' . tep_image_submit('button_in_cart_small.gif',

         } 
         else 
         { 
         $lc_text = tep_image_button('button_in_cart_small_faded.gif').'&nbsp;'; 
         } 
         break; 



        $list_box_contents[$cur_row][] = array('align' => $lc_align,
                                               'params' => 'class="productListing-data"',
                                               'text'  => $lc_text);
      }
    }

    new tableBox($list_box_contents, true);

    echo '    </td>' . "\n" .
         '  </tr>' . "\n";
