Many posters (including me) in this newsgroup don't do zope, so your best
option is to ask on a zope-related mailing list.

Replace these lines

with

          if bert in hiddens():
              continue # with the next publishable c

A 'continue' statement only affects the innermost loop, and as you don't
have any code that follows it in the for-element-loop it didn't have any
effect.
