When I inspect the JavaScript that is throwing the errors, I am not only noticing that Adrobat DC really wants you to terminate your JavaScript statements with semicolons, (which your code does some of the time), but I am also finding very strange constructs, some that would leave me to believe that even though your forms are technically not throwing any errors in the older versions of Acrobat, you might find that the forms are not actually behaving properly in the older versions. From what I can tell (someone can hopefully confirm this) is that the JavaScript interpreters in the older versions of Adobe are less strict about how they interpret the language, which is why your forms are working in the older versions, but are getting stopped by the latest interpreters in Acrobat DC. When you fix one set of syntax errors, a whole new set of syntax errors pop up. Upon Inspection of your PDF document in the Adobe DC JavaScript debugger, I am afraid there are just a whole bunch of syntax errors thrown.
