UBB.Developers Forums UBB.threads 7 Development How Do I? Integration question

I used this last year for our members when we bid new crews. We're going to be bidding again next week for our 2003 work schedules, but I'm getting an error.

Fatal error: Call to a member function on a non-object in /home/natcazjx/public_html/bidding/bidconfig.php on line 4



Here are the first four lines of my script I am building;

<?
require ("../forum/main.inc.php");

$user = $userob -> authenticate('U_Groups');


Any idea why I'm getting this error?


Thanks
