help register page

when i creat register page and i start it its say :

Notice: Undefined variable: GunzDB in C:\wampy\www\index.php on line 23

Notice: Undefined variable: GunzDB in C:\wampy\www\index.php on line 23

Notice: Undefined variable: 00---- in C:\wampy\www\index.php on line 23

Warning: odbc_connect() [function.odbc-connect]: SQL error: [Microsoft][Gestionnaire de pilotes ODBC] Source de données introuvable et nom de pilote non spécifié, SQL state IM002 in SQLConnect in C:\wampy\www\index.php on line 23
Can't connect the MSSQL server.

Look at like 23 and post that code from the warning I think it says it cant connect to the database (I havent dont anything GunZ related in a long time).
