  3. Heres what connects to the database. I took out some of the database info for obvious reasons

     

     

    <?

     

    /**

    * Connect to the mysql database.

    */

    $conn = mysql_connect("mysql11", "a9194245", "s") or die(mysql_error());

    mysql_select_db('a9194245', $conn) or die(mysql_error());

     

    ?>

     

  4. I got a login script from a site and its works good until you go to login. Its shows just a blank screen, and i tried putting the form on the top and i got thi error

     

    Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /home/a9194245/public_html/login.php on line 32

     

    Heres the code

     

    <?

     

    /**

    * database, if so it checks if the given password is

    * the same password in the database for that user.

    * match up, it returns an error code (1 or 2).

    * On success it returns 0.
