Permission problem

[subnet_rx]

I have read several articles, did some trial and error, and basically figured out many of my questions. At this point in my script, I have a question about usergroup_permissions. I got this code out of Psionic's tutorial, but it doesn't seem to work for me. Everyone is getting to the form. Here it is:

if ($_REQUEST['do']=='create_event' AND (!is_member_of($vbulletin->userinfo, 6) OR !is_member_of($vbulletin->userinfo, 76)))
{
	eval('$usernamecode = "' . fetch_template('newpost_usernamecode') . '";');
	if (!$_REQUEST['outcomes'])
	{
		eval('$picksbody = "' . fetch_template('picks_outcomes') . '";');
	}
	else
	{
		$o = $_REQUEST['outcomes'];
		for($i=0; $i<=$o; $i++)
		{
			$outcomes .= "<p><label>Outcome ".$i.":<input name=\"outcome[".$i."]\" type=\"text\" id=\"outcome".$i."\" size=\"64\" maxlength=\"127\" /></label></p>";
		}
		eval('$picksbody = "' . fetch_template('picks_new_event') . '";');
	}
}

Users in group 6 (me) and users not in either group still get the code executed in the function.
