Problemi in product_info.php

[southmodel]

Ciao a tutti, ho installato questo contr.

http://www.oscommerce.com/community/con ... arch,ezier

che permete di visualizzare nel file catalog/product_info.php un "confronto prezzi, ad esempio

retail price: 89.99
our price: 45.00
you save: 44.99 or 50%

nella pagina catalog/product_info.php bisogna trovare

<?php echo '<a href="' . tep_href_link(DIR_WS_IMAGES . $product_info['products_image']) . '" target="_blank">' . tep_image(DIR_WS_IMAGES . $product_info['products_image'], $product_info['products_name'], SMALL_IMAGE_WIDTH, SMALL_IMAGE_HEIGHT, 'hspace="5" vspace="5"') . '<br>' . TEXT_CLICK_TO_ENLARGE . '</a>'; ?>
</noscript>
</td>
</tr>
</table>
<?php
}
?>

da sostituire con:

<?php echo '<a href="' . tep_href_link(DIR_WS_IMAGES . $product_info['products_image']) . '" target="_blank">' . tep_image(DIR_WS_IMAGES . $product_info['products_image'], $product_info['products_name'], SMALL_IMAGE_WIDTH, SMALL_IMAGE_HEIGHT, 'hspace="5" vspace="5"') . '<br>' . TEXT_CLICK_TO_ENLARGE . '</a>'; ?>

in effetti funziona, se ho inserito il nuovo prezzo nella scheda articolo in admin appare il "confonto prezzi", ma se non ho inserito il prezzo di confonto la pagina è completamente "sballata", ho fatto diverse prove ma non riesco ad ottenere un buon risultato, ad esempio se dopo

<?php echo '<a href="' . tep_href_link(DIR_WS_IMAGES . $product_info['products_image']) . '" target="_blank">' . tep_image(DIR_WS_IMAGES . $product_info['products_image'], $product_info['products_name'], SMALL_IMAGE_WIDTH, SMALL_IMAGE_HEIGHT, 'hspace="5" vspace="5"') . '<br>' . TEXT_CLICK_TO_ENLARGE . '</a>'; ?>

succede esattamente il contrario, gli articoli normali vengono visualizzati correttamente, gli altri sfalsati.....
