woopra or wordpress stats and phpbb forums

Hi,
I’ve added a phpbb forum http://www.heskethmediation.com/ukmediationforum to my wordpress blog http://www.heskethmediation.com
Neither wordpress stats not woopra plugins are counting visitors to the forum. I guess I need some script in the footer for the forum but does anybody know what the script is and which phpbb file it needs to go in?
Many thanks
