Going Live!
Finally, after your form has been added and configured via the Form Tools interface, you just need to make one final change to push it live. On your form page, again change the ft_api_init_form_page function line to this (where X is your form ID):
$fields = ft_api_init_form_page(X);
(All you did was remove the second parameter). Now, after you've revisited the "thankyou" page to ensure that sessions were emptied, all your form submissions should be stored in Form Tools!
