Do you know if MySQL is throwing errors? Note that you can use mysql_error() to check.

http://php.net/manual/en/function.mysql-error.php

 

Also note that your queries are vulnerable to SQL injection attacks. If you haven't done so already, you'll want to look into mysql_real_escape_string().

In your queryies, add a check for mysql_errors())

$result = mysql_query($sql,$con) or die(mysql_errors());
