good day to all, 
Sir/Madam my $_GET['criteria_id']; not working, cant display.

////// this is the code i use to display the data from table "criteria" and the colum are: [criteria_id, criteria] and the name of my database: autotab 

<?php
            require_once 'connect.php';
            $idz=$_POST['criteria_id'];
            $wh=mysql_query("select * from criteria");
            while($loop=mysql_fetch_array($wh)){
                $ca=$loop['criteria_id'];

                echo    
                        '<div class="loop"><a href="?cont=ssw.php&id='.$loop['criteria_id'].'">'.$loop['criteria'].'&nbsp;.'.$loop['criteria_id'].'</a></div>';

            }    //the <a href=""></a> is good but when i click it to call the ssw.php which i want this criteria_id and criteria will display to the page ssw.php it doesn't work.
            ?>
///////////////// please take a look of this code below of home.php and ssw.php ///////////////

-----------
home.php -code.

<?php session_start();?>
    <?php
        if(isset($_GET['cont'])){
            $Cont=$_GET['cont'];
        }
        else $Cont='home.php';
    ?>

I see you are trying to get a post value, but I don't see a form in your code?

Sidenote: The way you are writing your code will make it really hard to debug and troubleshoot. You should think about seperating your html from you php.
