help with conditional

[sabret00the]

PHP Code:

    if (!($group_info['leaderid'] == $vbulletin->userinfo['userid'] AND $vbulletin->bf_ugp['grpspermissions']['groupspostedit']) AND !($vbulletin->bf_ugp['grpspermissions']['groupsmoderator']))
    {
        $mod_options = "
            <form action=\"postings.php\" method=\"post\">
                <strong>Moderation</strong>: 
                <select name=\"do\">
                    <option value=\"\" selected=\"selected\">----------</option>
                    <option value=\"cls\">Close Thread</option>
                    <option value=\"del\">Delete Thread</option>
                    <option value=\"stk\">" . (($group_info['stuck']) ? "Unstuck" : "Stick") . " Thread</option>
                </select>
                <input class=\"button\" id=\"inlinego\" type=\"submit\" value=\"Go\" />
                <input name=\"threadid\" value=\"$t\" type=\"hidden\">
                <input name=\"groupid\" value=\"$g\" type=\"hidden\">
                <input name=\"url\" value=\"viewthread.php?g=$g&amp;t=$t\" type=\"hidden\">
            </form>
        ";
    }
    else
    {
        $mod_options = FALSE;
    } 


the conditional is if your userid is the same as the leaderid AND you're usergroup permissions allow you to edit groups OR you're a groups moderator (as set within the usergroup options) then display the info, otherwise don't.

however i can't get this to work. what am i doing wrong?
