Validating Custom Item Required Responses

[jarvis24]

Note in response to the orginal post (see above), one could change the syntax in this custom item to require that just one or more questions be answered (as opposed to all). I didn't test it, but you should be able to simply replace all the instances of "||" (meaning or) with "&&" (meaning and). This would then generate the feedback message only if no questions were answered.
