I'm setting up some forms for a client and would like to include a custom field value in the notification email they receive.
The custom field is set by post author when the post is created and NOT through data submitted in the form. I can't get the value of the field to appear in the notification email though. I've tried adding a hidden and/or an admin-viewable only field to the form and then inserting the value in the notification email with no luck.
Am I missing something obvious?
