shoutbox permissions

[Chadi]

I use a shoutbox from www.cbox.co.za

This is my code

<table border="0" cellpadding="0" cellspacing="0" width="100%">
<tr>
	<td align="center" style="border-style:solid; border-width:1px; " bgcolor="#F5F5FF" bordercolor="#C0C0C0">
<table border="0" cellpadding="0" cellspacing="0" width="100%">
<tr><td style="border-bottom-style: solid; border-bottom-width: 2px">
<iframe frameborder="0" width="100%" src="http://cbox.co.za/box/?boxid=43&boxtag=786&sec=main" marginheight="0" marginwidth="0" scrolling="yes" name="cboxmain" allowtransparency="yes" style="border: #ababab 0px solid" height="200"></iframe></td></tr>
<tr><td>
<if condition="is_member_of($bbuserinfo,1,3,4,8,11)">
You must be registered and confirmed active account to use the shoutbox
<else />
<iframe frameborder="0" width="100%" height="50" src="http://cbox.co.za/box/?boxid=439&boxtag=7868&sec=form&wname=68&wemail=68&wmsg=175" marginheight="0" marginwidth="0" scrolling="no" name="cboxform" allowtransparency="yes" style="border: #ababab 0px solid; border-top: 0px;"></iframe>
</if>
</td></tr></table></td>

The red part is what was suggested to use to restrict access to the groups listed. Problem is it only works on non registered users but no other groups in the list. How do I correct this?
