If so, how do you go about it?
I've tried just popping the module call 

<jdoc:include type="modules" name="productsubnav" style="xhtml" />

I also tried:

<?php$document   = &JFactory::getDocument();$renderer   = $document->loadRenderer('module');$options   = array('style' => 'raw');$module    = JModuleHelper::getModule('mod_comments_comments');$module->params   = "heading=2\nlimit=10";echo $renderer->render($module, $options);?>

Neither worked though. I'm trying to display a list of articles beneath the current item (factsheets etc)

Many thanks
