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();
