in reply to Reading form data and printing variables using CGI.pm

Greetings cal,

You're on the right track. You just need to define what $Firstname is going to be.

my $Firstname = param('Firstname');

Put that somewhere in front of your print statement and you're done.

    But how does the variable become associated to the HTML line? 'is the value of $Firstname', Thanks 
    

<code>
#!/usr/local/bin/perl -w
use strict;
use diagnostics;
use CGI qw(:standard);
my $Firstname = param('Firstname');

print header(), 
        start_html(-title=>"CGI.pm Example Script"), 
                                 h1('Hello World!'), 
                       'is the value of $Firstname', 
        end_html(); 

exit (0);

      Greetings cal,

      In Perl, using a single quote simply reads a string literally, but a double quote interprets a string. In your code, you have single quotes around the string where you use $Firstname. So what gets printed is literally "$Firstname". You actually want Perl to interpret the variable, so...

      print header(),
  start_html(
    -title => 'CGI.pm Example Script'), 
    h1('Hello World!'), 
    "is the value of $Firstname",
  end_html();

      Huh? 
      my $PERL_FAQ = "butterscoth";
print 'my $PERL_FAQ \n';
print "my $PERL_FAQ \n";
