Please help with this code

this code was from old fckeditor and like to change it with classeditor but it seems not to work:

<td class="main"><?php echo TEXT_VENDORS_PROD_COMMENTS; ?></td>
<td class="main"><?php echo tep_draw_separator('pixel_trans.gif', '24', '15') . ' ' . tep_draw_textarea_field('vendors_prod_comments', 'soft', '70', '5', (isset($vendors_prod_comments) ? $vendors_prod_comments : tep_get_vendors_prod_comments($pInfo->products_id))); ?></td>
</tr>

This is what I tried but nothing happens:

<td class="main"><?php echo TEXT_VENDORS_PROD_COMMENTS; ?></td>
<td class="main"><?php echo tep_draw_separator('pixel_trans.gif', '24', '15') . ' ' . tep_draw_textarea_field('vendors_prod_comments, 'soft', '70', '10', (isset($vendors_prod_comments) ? $vendors_prod_comments : tep_get_vendors_prod_comments($pInfo->products_id, 'class="ckeditor"');
?>
