500 error

[filch]

    That's just the thing Ben, I am not passing a form id to the page from anywhere other than the normal formtools code at the top of the page, as this is on the home page. When I put in the code to echo the id, it shows me a blank page because there is no form id. So I really do not see where is is getting passed and id other than from the normal code:

Code:

<?php
require_once("/home/zuka/public_html/support/formtools/global/api/api.php");
//ft_api_delete_unfinalized_submissions(15, false);
$criteria = array("email" => $_POST["email"]);
$fields = ft_api_init_form_page(15);
ft_api_start_sessions();
$fields = isset($_SESSION["form_tools_form_data"]) ?
  ft_strip_tags($_SESSION["form_tools_form_data"]) : array();
$params = array(
  "submit_button" => "submit",
  "next_page" => "subscribe-thanks.php",
  "form_data" => $_POST,
  "finalize" => true
    );
ft_api_process_form($params);
?>

Form with id 15 does exist ( see attached ) so I do not know what is causing the error.
