No dynamic subject?

Hi,

I'm using Joomla 2.5.6 with 4.0 RC3.4.1

I want to have an dymanic subject so i placed in "Before Emails Code":

<?php
$form->data['onderwerp'] = "Aanmelding van {$form->data['input_text_3']} op  {$form->data['input_checkbox_group_2']} ";
?>

But in the email setup i only see Dynamic to, reply to name, reply to email.
Where is the dynamic subject?

Hi Sjorzzzie,

Please change to the Advanced (default) Form Wizard using the Form Wizard Mode option on the form General tab (click the form name link in the Forms Manager to see this tab).

Note that you don't need to change back again, if you do you may lose some form edits.
