Edit button on portal page

[Skiilz]

Hey I'm trying to add the edit button to my portal page but I can't seem to find the correct link variable for the thread ID...
Here is the code I'm trying and I get "http://postbomb.net/forums/editpost.php?pid="

PHP Code:

<if in_array($GLOBALS['mybb']->user['usergroup'], array(4,8)) then> <span class="smalltext" style="float: right;"> <a href="{$mybb->settings['bburl']}/editpost.php?pid={$post['pid']}"><img src="{$mybb->settings['bburl']}/images/psbliss/english/postbit_edit.gif" alt="Full Edit" /></a> </span> </if>
