[LON-CAPA-users] can I identify an empty submission?

HI All,

If in a multiple choice question a student clicks the Submit Answer button without choosing an answer, I know there is no visible status message that appears for the student, but I'm wondering if there is some type of code that can be identified somewhere?  I have a problem with 25 parts, each of which has a multiple choice question and I'm looking for a way of identifying if a student hits submit on any of those parts without selecting an answer. Is there Lon-Capa magic for that? Thanks!

(and if anyone want to know WHY I'd want to do that, I'll be happy to share)
