joomla mambots on virtuemart

two ways

(1) vm config Enable content mambots / plugins in descriptions? click + done

(2) if (1) doesn't work do this

open the vm template file of the page where you want to have the mambot operating (i.e. flypage.tpl.php)

within the php, before the first piece of html type this: ob_start();

within the php, at the very bottom of your page type this: $contenthtml=ob_get_contents();ob_end_clean();echo JHTML::_('content.prepare',$contenthtml);

that should do it. otherwise keep googling.
