Session variables not sent to database

I created some new fields in the checkout page and I'm trying to save them as session variables, have them post to the database on the confirm page, and then show up in the email. I've already posted with questions on how to do this, so I thought I new how. I created the form fields, created the session variables by going to eCart > General > set session value. I used the lightning bolt to select the trigger as the form element and the same thing for the value. And I opened the confirm page and created a dataassist single file upload behavior. Lastly, I added the session variable strings in the email. Nothing is showing up in either the email or the database, so I can't figure it out. I've attached my checkout.php page.

the checkout form posts to the confirm page.

When adding form elements to the checkout form there are 3 steps you must follow:

1) Add the form element to the checkout page:

<input name="newElement" id="newElement" type="text" />

2) Add a hidden form element on he confirm page with the same name, set to capture the value from the checkout page:

<input name="newElement"  id="newElement" type="hidden" value="<?php echo((isset($_POST["newElement"]))?$_POST["newElement"]:"") ?>" />

3) Add the set session value behavior tpo the confirm page to capture the value posted from the checkout page:

<?php

if (!session_id()) session_start();

if($_SERVER["REQUEST_METHOD"] == "POST")     {

  $_SESSION["newElement"] = "".((isset($_POST["newElement"]))?stripslashes($_POST["newElement"]):"")  ."";

}

?>
