Only send back one header at a time. Test for request_method eq to POST and then send back the file.

Like the following:

#!/usr/bin/perl -w

use CGI qw(:standard);

use strict;

if (request_method() ne 'POST') {
    print header;
    print start_html('Download'),
      h1('Download'),
      start_form,
      p,
      "Feet? ",   textfield(-name => 'feet',   -size => 5),
      "Inches? ", textfield(-name => 'inches', -size => 5),
      p,
      submit(-value => 'Create File'),
      end_form,
      hr,
      end_html();

} else {

    my $feet     = param('feet');
    my $inches   = param('inches');
    my $filename = param('feet') . param('inches') . '.txt';

    my $tape = <<"END_FILE";
It is $feet ft. $inches in.
END_FILE

    print "Content-Type: application/octet-stream; name=$filename\n";
    print "Content-Disposition:attachment; filename=$filename\n\n";
    print $tape;

}

Also, please use strict.
