Expression syntax help request

Hi! I'm looking for some help with the correct syntax to combine these two expressions (each of which works great by itself):

Code:

(!empty($forum) AND in_array($forum['parent_node_id'], array(245,44,247,248)))
OR (!empty($category) AND in_array($category['node_id'], array(245,44,247,248)))

and...

Code:

XenForo_Template_Helper_Core::helperIsMemberOf($visitor, 6) == false

So the end result, we want the widget displayed only in the nodes and categories listed, and only if the user is not in usergroup 6.

Thanks!

 

Holy cow I think I got it!!

Code:

(!XenForo_Template_Helper_Core::helperIsMemberOf($visitor, 6)) AND
((!empty($forum) AND in_array($forum['parent_node_id'], array(245,44,247,248)))
OR (!empty($category) AND in_array($category['node_id'], array(245,44,247,248))))
