The values returned by check-boxes are only true or false (checked or not checked). If you need to have the captions of all values checked in a notification, there are several ways to accomplish the task. I would use a hidden field. Build a behavior that populates a hidden multi-line text box with the value of what is in the hidden multi-line input field plus a space plus the caption of the check-box when it is checked. Run the behavior behind the submit button rather than on the individual check-boxes so your users can change their minds without giving false-positives.Then you can use the hidden field in your email notification.
Have a great day!
