You need to go back and look at the example again.  Actually, I have the
book, so if you have a page number I can look at it.  But your problem is
that you need to define the soubroutine parse_form_data, just as the error
message tells you.  You should also add the -w switch to the shebang line:

#!/usr/local/bin/perl -w

sub parse_form_data {
        #subroutine stuff
}

You also need to define *simple_form, which is supposedly being passed to
the parse_form_data subroutine.  I suggest going back to the basics.  Get
the book "Learning Perl," and read the online documentation at
http://www.perl.com/.

Good luck,
