I did not understand very well, my English is very bad and I use a translator, so this would be correct?
Code:
<!--yobromofo.com flashing message-->
<vb:if condition="$bbuserinfo['pmunread']">
<a href="private.php{vb:raw session.sessionurl_q}"><img border="0" src="images/newpm.gif" width="24" height="11"></a>
<else />
<vb:if condition="$notifications_total">
</vb:if>
</vb:if>
<!--yobromofo.com end flashing message-->
thank you very much
