Just for other people that may have this problem...
The above fixed the Description but the price was still not in bold, and the price had no css class, so I had to edit the product_listing.php
The columns are defined by the following in the \includes\modules\product_listing.php
$lc_text = '<h3 class="itemTitle"><a href="' . zen_href_link(zen_get_info_page($listing->fields['products_id']), ($_GET['cPath'] > 0 ? 'cPath=' . $_GET['cPath'] . '&' : '') . 'products_id=' . $listing->fields['products_id']) . '">' . $listing->fields['products_name'] . '</a></h3><div class="listingDescription">' . zen_trunc_string(zen_clean_html(stripslashes(zen_get_products_description($listi ng->fields['products_id'], $_SESSION['languages_id']))), PRODUCT_LIST_DESCRIPTION) . '</div>';
}
break;
case 'PRODUCT_LIST_MANUFACTURER':
$lc_align = '';
$lc_text = '<a href="' . zen_href_link(FILENAME_DEFAULT, 'manufacturers_id=' . $listing->fields['manufacturers_id']) . '">' . $listing->fields['manufacturers_name'] . '</a>';
break;
case 'PRODUCT_LIST_PRICE':
$lc_price = zen_get_products_display_price($listing->fields['products_id']) . '<br />';
$lc_align = 'right';
$lc_text = $lc_price;
There would have been a number of ways to edit this inorder to change the font, etc, but what I changed was:
$lc_text = '<h3 class="itemTitle"><a href="' . zen_href_link(zen_get_info_page($listing->fields['products_id']), ($_GET['cPath'] > 0 ? 'cPath=' . $_GET['cPath'] . '&' : '') . 'products_id=' . $listing->fields['products_id']) . '">' . $listing->fields['products_name'] . '</a></h3><div class="listingDescription">' . zen_trunc_string(zen_clean_html(stripslashes(zen_get_products_description($listi ng->fields['products_id'], $_SESSION['languages_id']))), PRODUCT_LIST_DESCRIPTION) . '<br />';
}
break;
case 'PRODUCT_LIST_MANUFACTURER':
$lc_align = '';
$lc_text = '<a href="' . zen_href_link(FILENAME_DEFAULT, 'manufacturers_id=' . $listing->fields['manufacturers_id']) . '">' . $listing->fields['manufacturers_name'] . '</a>';
break;
case 'PRODUCT_LIST_PRICE':
$lc_price = zen_get_products_display_price($listing->fields['products_id']) . '<br />';
$lc_align = 'right';
$lc_text = $lc_price . '</div>';
