Skip empty fields in Success Page?

[davidsho]

I have a form with a dozen or so list boxes; users select one or more items from one or more list boxes. The Form Processing email lists data only for those list boxes for which selections have been made, ignoring those where no selection was made. This is ideal. Example:
Pre Ballet : Saturday,9-9:45am
Ballet I : Friday 5:45-6:45pm
Register : Register Now!
This response skipped the Beginning Ballet list box, which comes between the Pre Ballet and Ballet I boxes.

I would like to do the same when processing the variables in the success page. My current set up for the Success Page lists every list box by name in text (e.g. "Pre Ballet:") followed by the variable indicator (e.g. $Pre_Ballet) The response includes every list box, even if no selection is made:
Pre-Ballet: Saturday,9-9:45am
Beginning Ballet: $Beginning_Ballet
Ballet I: Friday 5:45-6:45pm


I would like it to skip the Beginning Ballet box as the form processing email does. Is this possible?

Thank you!

There is currently no standard solution for this, so this will require a custom script.

OK. Thank you.
