[PHP] _GET question

[Pushpinder Singh Garcha]

Hello All,

   My application has a search / query feature where in the user 
selects the search criteria and is displayed a page containing the 
reults. The user must also be allowed to edit these results and save 
them later on. On the results page I use the following logic,

//
//     START OF PSEUDOCODE
//
<?
session_start()
if ($submit)
  {
     yada yada yada
   Update the database with the changes the user has made in the form

    $value = $_GET['val'];
    echo ": ".$value."<br>";
   $UpdateString = "UPDATE contacts SET

   ... ....
....
.....
....
where WHERE `company`  = '$value' ";
        
  }

elseif (isset(_SESSION['validuser'])) {

    display the form with the results of the search
<form name="form1" method="post" 
action="full_profile_1.php?val=$company">
...
...
...
...
</form>

}

elseif ( ! isset(_SESSION['validuser'])) {

   // display an error page asking the user to login

}

//
//    END OF PSEUDOCODE
//
Can some one tell me if the action parameter of the form is correct ? 
Since in the first part of the if() statement when I try to retrieve 
the value of $_GET['val'] I do not get anything.

All suggestions are welcome. Thanks in advance
