    My GTN php game is showing a blank page

    Hey guys i'm upgrading guess the number game i created, i saved the number on a text file but i had problems if many users played the game simultaneously because the number gets overwritten so now i want to use a database to store the number where a nickname, ip address, generated number and user id will be stored. But now the game shows blank pages can you help? Here's the source code
    PHP Code:
    <html>
    <head>
    <title>wapEvening | Guess the number game</title>
    <link rel="stylesheet" type="text/css" href="includes/style.css"/>
    </head>
    <body>
    <?php
    require_once "includes/header.inc";
    require_once     "includes/con.inc";
    $ran = rand(1,50);
    $ip  = $_SERVER['HTTP_X_FORWARDED_FOR'];
    $insert = "INSERT INTO *** (id,ip,number)
    VALUES(NULL,    {$ip},{$ran})";
    $enter = @mysql_clean(mysql_query($insert));
    print     'Welcome to guess the number game, you have 5 chances to guess the number between 1 and 50
    (included) you loose 10 points for every incorrect number you guess, you get a bonus of 20
    points if you guess correct number first time'    ;
    $nick  = print '<input type="text" size="5" maxlength="10" name="nick">';
    $guess = print '<input type="text" size="1" maxlength="1" name="guess">';
    print     "\nEnter :\n<form action=\"gtn_answer.php\" method=\"POST\">Nickname : ".$nick."\nYour
    guess : "    .$guess."</form>";
    ?>
    </body>
    </html>

    You have a fatal error on $enter = @mysql_clean(mysql_query($insert)); -> remove @ to see what is the problem ....
    Better use Sessions instead database for a little game ...

      For example:
      PHP Code:
      function mysql_clean($var) {
      $var = mysql_real_escape_string($var);
      return       $var;
      }

        You cant clean the query ....
        and here its a simple example ...

        PHP Code:
        <?php
        // author : Ionutxp
        // of course , whatever

        session_start();
        error_reporting(0);

        if (isset(        $_GET['action']))
                    $act = $_GET['action'];
        else
                    $act = '';

        function         check_game()
        {
            if (!isset(        $_SESSION['game_number']))
            {
                return         'INACTIVE';
            }
            if (isset(        $_SESSION['game_number']) && $_SESSION['game_errors'] < 5 && !$_SESSION['game_guessed'])
            {
                return         'ACTIVE';
            }
            if (isset(        $_SESSION['game_guessed']) && $_SESSION['game_guessed'])
            {
                return         'WON';
            }
            if (isset(        $_SESSION['game_errors']) && $_SESSION['game_errors'] > 4)
            {
                return         'LOSE';
            }
                    print_r($_SESSION);
        }
