Try running this:

  #!/usr/bin/perl

  use CGI;
  use Data::Dumper;

  my $q = CGI;
  print Dumper [$q->checkbox(-name => "foo")];
  print Dumper [$q->end_form];

This prints out:

  $VAR1 = [
            '<input type="checkbox" name="foo" value="on" />foo'
          ];
  $VAR1 = [
            '<input type="hidden" name=".cgifields" value="foo" />',
            '</form>'
          ];

You can see that end_form is now actually returning two values (including
a hidden form.)  TT treats this as a list ref.  You probably want to
simply join them, which can be done like so:

  [% query.end_form.list.join %]

The .list. bit ensures that end_form is a list (even if it has just one
element.  The virtual methods are described in the manual here:

Hope that's helpful.

Mark.
