How can I have a notification email only include fields that were entered

We have a form that has fields for three departments. We would like to program the notification emails to ONLY shot the fields that have been entered when someone fills out the form. See below for example the fields marked out in red were not entered because they are hidden fields. How can we get them not to display in the submission? thanks!

You must be referring to the method / feature described in the user guide 

-How-to-Hide-Empty-Fields-on-Email-Alerts

Please let us know if this will not work for you.

Thanks.
