Client Load Failure

[MsftsRepKing]

Warning: mysql_query() [function.mysql-query]: Access denied for user 'ODBC'@'localhost' (using password: NO) in C:\xampp\htdocs\client\disconnected.php on line 9

Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in C:\xampp\htdocs\client\disconnected.php on line 9

Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\client\disconnected.php on line 10

The client will be loading but then will stop and this will pop up. Whats the fix?
