You should consider to use start_form() and end_form() from CGI to start and finish your HTML form.

You can save many prints if you print a list of $cgi->... elements.

print $cgi->header(),
  $cgi->start_html('title'),
  $cgi->start_form(),
  #... your form here
  $cgi->end_form(),
  $cgi->end_html(),
;

Update: Maybe you should have a look at a templating system like HTML::Template as well. Using a templating system helps you to separate your HTML content from your perl code.
