Ummm... the warning mesage states "MySQL-Link resource", ergo it has nothing to do with the database name.
mysql_select_db() accepts 2 arguments. The first is the name of the database. The second is the MySQL link identifer returned by either mysql_connect() or mysql_pconnect() and is optional. If it's not specified, PHP will try to use any available and open MySQL link. Either drop the $joesauto variable from the argument list or try this:
$joesauto = mysql_connect($your_hostname, $your_username, $your_password) or die("Unable to connect to MySQL on $your_hostname");
mysql_select_db($kenston,$joesauto) or die("Unable to select database $kenston");
HTH!
