Ive done this now and if anyone is interested here the code that I placed in the category Template
Just after this code around line 180 - 190
<span class="FlexibleCategiryTitleSPAN"><?php echo JText::_('COM_VIRTUEMART_SEARCH') ?>: <?php echo $this->keyword; ?></span>
</div>
<?php } ?>
Add this;
<?php
$jinput = JFactory::getApplication()->input;
$trigger="virtuemart_manufacturer_id";
$mid = $jinput->get->get($trigger);
if (!empty($mid))
{
echo '<div class="manufacturer-description>';
echo '<p>'.$this->products[0]->mf_desc.'</p>';
echo '</div>';
}
?>
Does this look OK?
Anybody come up with a simpler solution?
Thanks
