i don't know if i kept track of this conversation, but here is some help.. (Someone mentioned the fact that they needed help knowing how to correct their code...)

Code:
$_GET['name'];  //this would get a variable called "name" that was in the query string (address bar) or from a method="get" 
   // for example  user_setup.php?name=rob      "rob" would be returned..

$_POST['name'];  //this would get a variable called "name" that was posted from a form with  method="post" in the <form> tag.

Hope this helps a bit...

(the code above has no Flash functions.. only php, so i don't know if it helps at all :P)
