I am going to produce a web page via CGI Pretty.
But nothing after I run the script. The web page size is 0.
Code:
#!C:/Perl/bin/perl

use strict;
use CGI::Pretty qw( -debug );
use CGI::Carp qw( fatalsToBrowser );

my $q = new CGI;

my $pay = $q->param(payment=>"discover","master","check");
my $pay_text;

if ( $pay eq "discover" ) {
 $pay_text = "Discover Card";
}
elsif ( $pay eq "discover" ) {
 $pay_text = "Master Card";
}
elsif ( $pay eq "check" ) {
 $pay_text = "by check";
}
else {
 $pay_text = "unknown method";
}

print $q->header,

   $q->start_html( -title=>"Welcome",
           -bgcolor=>"pink"),

   $q->p( "Your name is ", 
       $q->b("name")),

   $q->p( { -style=>{yext-decortation:underline},
        "Your age is ",
        $q->textfield(-name=>"age")),

   $q->p( "Your method of payment is ",
       $q->span($pay_text),-style=>{color=>"blue"})
   $q->end_html;
