It can't complete the first query for some reason.

Try replacing

$db=mysql_connect($servername,$dbusername,$dbpassword);
mysql_select_db($dbname);

with

$db=mysql_connect($servername,$dbusername,$dbpassword) or die("can't connect");
mysql_select_db($dbname) or die("can't get db");

and tell me if you still get the same error or a different error.
