Thanks for that. It was not totally the right answer but you lead me in the right direction.
Because it was not a link preset in the vb database, I had to set it to:
<td class="vbmenu_control"><a href="xxx">yyy</a></td>
where xxx was the full URL and yyy was the name of the link to be displayed.
and removed the .php?$session[sessionurl]
Thanks again, have it exacly as I wanted it
