Error browsing through teammembers

Hi everyone

I think there is an error when browsing through the list of members of teams with more than 1000 entries.
If you click on this link http://setiweb.ssl.berkeley.edu/team_display.php?teamid=30204&sort_by=expavg_credit&offset=1000 the members 1001 - 1020 from Planet3DNow will be shown. But when you click on the Next 20 http://setiweb.ssl.berkeley.edu/team_display.php?teamid=30204&sort_by=expavg_credit&offset=1020 link the following error message shows ups:
Fatal error: Call to undefined function: page_head() in /disks/koloth/raid5_b/users/boincadm/projects/sah/html/user/team_display.php on line 11

I tried it with other teams too, getting the same result: if the offset parameter in the URL is higher than 1000 the sites fail.

Greetings
mike

edit:
sorry for posting in the preferences forum, wishlist would have been the better one. maybe someone can move it. thanks
