You may need to post a code sample. Neither the sample above or the
tutorial contain the phrase "must_match".

I will note that the password example is outdated. A better way to do
the same thing is with "FV_eq_with":

http://search.cpan.org/~markstos/Data-FormValidator-4.63/lib/Data/FormValidator/Constraints.pm#FV_eq_with

I'm CC'ing the DFV::Tutorial author, who may wish to update the example.
