[ww-devel] gateway issue

[P. Gavin LaRose]

Hi all,

Follow-up: I believe this is in the following lines (c. 2170) in
GatewayQuiz.pm.
  foreach my $curr_field ( @curr_fields ) {
          print CGI::hidden({-name=>$curr_field,
			     -value=>$self->{formFields}->{$currField}});
  }

The value in $self->{formFields}->{$currField} is a "\0" joined string of
answers from the form.  Thus, I think the solution is to take
  foreach my $curr_field ( @curr_fields ) {
  	  foreach ( split(/\0/, $self->{formFields}->{$currField} ) {
                  print CGI::hidden({-name=>$curr_field,
			             -value=>$_});
	  }
  }

If anyone sees something conspicuously wrong about that, please let me
know.

Thanks,
Gavin
