I hope this helps you . I have an object which looks like this , To get the content of $result, you have to:
code :
print $result->{success};
print $result->{error};
% my $result = {
%   success => 0,
%   errorType => 'SHIRT_ERROR',
% };
% $m->redirect( make_uri('error_handler', $result), 302);
/error_handler?errorType=SHIRT_ERROR&success=0
<%class>
  has 'success';
  has 'errorType';
</%class>
<%init>
  if ($.success eq "0") {
    print $.errorType;
  }
</%init>
<%init>
use JSON;

my $result;
$result->{success} = 0;
$result->{error} = {errorType => "SHIRT_ERROR"};

my $h = {
  result => encode_json $result
};

$m->redirect(make_uri('/error_handler', $h), 302);
</%init>
<%class>
  has 'result';
</%class>
<%init>
  use JSON;

  my $result = decode_json $.result;

  print dh $result;
</%init>
http://localhost:5000/error_handler?result=%7B%22success%22%3A0%2C%22error%22%3A%7B%22errorType%22%3A%22SHIRT_ERROR%22%7D%7D

Any of those help For tasks like this, the combination of WWW::Mechanize and HTML::TokeParser is your friend. The former helps you navigate by clicking buttons, links, etc. and the latter slices and dices the HTML.
In this case, you simply navigate to the page, scan the data for 'input' tags (i.e. a 'checkbox' is a type of 'input') and then test each input to see whether the 'name' attribute matches the one you're after. Once you've found the correct 'input' tag, then you just grab the value of the 'checked' attribute, which you can then use a you like.
code :
use WWW::Mechanize;
use HTML::TokeParser;

my $checkbox_name = "cb";
my $url = 'http://some_url/';

my $page = WWW::Mechanize->new(autocheck =>1);
$page->get($url);
my $pagedata = HTML::TokeParser->new(\$page->{content});

while (my $token = $pagedata->get_tag("input")) {
    my @tokenarray = @$token;
    my $attr_ref = $tokenarray[1];
    my %attr = %$attr_ref;

    # dump the contents of the hash
    foreach my $k (keys %attr) {
        print "$k: $attr{$k}\n";
    }
    print "\n";

    if ($attr{name} eq $checkbox_name) {
        print "found it!\n";
        print "status = ", $attr{checked}, "\n";
        last;
    }
}

hope this fix your issue Mason has a large number of dependency modules, but this and all of the dependencies can be installed from the command line using the cpan installer (I just verified this would work on Windows 7), though cpanm (yes, "cpanm", not a typo) seem to be the preferred install method mentioned in the module documentation. See install section of docs on CPAN (http://metacpan.org/pod/Mason).
Also, since you may be running CPAN on Windows, be aware that some modules may not compile correctly using CPAN and it may be necessary to alternate between the CPAN and ActiveState PPM module installers to get some of the dependency modules installed before Mason can be installed.

should help you out Since you're only wanting to generate a table, you could do this easily without using HTML::Mason:
code :
use HTML::Entities;
use Mail::Sendmail;
use MIME::Lite;
use Term::ANSIColor;
use Time::localtime;

my $ti = localtime;
my ( $day, $month, $year ) = ( $ti->mday, $ti->fullmonth, $ti->year );

# DEFINE A HASH
my %coins = ( "Quarter" => 25, "Dime" => 10, "Nickel" => 5 );

my $html = '<table border="1">
<thead><th>Keys</th><th>Values</th></thead>
<tbody>';

while ( my($key, $value) = each(%coins)) {
    $html .= "<tr><td>$key</td><td>$value</td></tr>";
}
$html .= "</tbody></table>";

my $greeting = 'Please direct any questions to <a href="mailto:abc@mydomain.com">MyEmailID</a><br><br>';
my $outtro = '<br><br>See yas later, alligator!';

$html = $greeting . $html . $outtro;

$msg = MIME::Lite->new(
    from    => 'abc@mydomain.com',
    To      => 'def@mydomain.com',
    Subject => 'Report',
    Type    => 'multipart/related'
);
$msg->attach(
    Type => 'text/html',
    Data => qq{
        <body>
        <html>$html</html>
        </body>
    },
);

MIME::Lite->send( 'smtp', 'xxxs.xxxx.xxxxx.com' );
$msg->send;

this one helps. In Mason, your Perl code needs to be inside your tags. Anything outside of a tag is just content to be included in the output. So you want something like:
code :
<%init>
  use Digest::SHA qw(sha256_hex);
  my $message = 'random content';
  my $encryptedMsg = sha256_hex($message);
</%init>

will be helpful for those in need You're currently reading in a text file. You should binmode first for non-text (like PDF). And, never use indirect object syntax.
