First as you are using CGI in exported function and OO mode which is problematic. You should use one or the other.

You have not shown us where you are (? not) outputing a valid header that lets the browser know that this is html to display. You can use CGI.pm's header() method. Try this:

#!/usr/local/bin/perl
use CGI qw/:standard/;
use File::Basename;

print header();

print_return_page_top();
print_results();
print_return_page_bottom();

### subs ###
 
sub print_results {
    my $file = param('upload');
    my $time = time;    
    unless ($file) {
        print h2("No file uploaded.");
      return;
    }
    ($base,$path,$type) = fileparse($file,'\..*');
    my $uploaded_path = "\\path\\to\\uploaded_files\\";
    $uploaded_path .= $base;
    $uploaded_path .= "_";    
    open FILE, ">$uploaded_path$time$type";
    binmode FILE;
    while(read($file,$buffer,1024)) {
        print FILE $buffer;
    }
    print h2('Success!'), p("$file has been uploaded.");
}

sub print_return_page_top { print h1('Top of page') }

sub print_return_page_bottom { print h3('Footer') }
