Adding usergroup id numbers

[Morning Glory]

How would I add more usergroup IDs to this so I can add the permissions to other groups? I tried separating by using commas and that didn't work.

<if condition="$bbuserinfo[usergroupid] == 6">
<tr><td class="vbmenu_option"><span onmouseover="this.style.cursor='hand';" onClick="window.open('modcp/banning.php?do=banuser&userid=$post[userid]','ban','width=500,height=375,scrollbars=yes')"><b >Ban User $post[username]</b></span></td></tr></if>
