Hi, I have a script that's supposed to take 5 or less files and upload them to a specified directory. The program seems to work but once i check the files i get errors or the file just won't load. Here is the script: 
#!/perl/bin/perl

use strict;
use CGI;
use File::Basename;
use Fcntl qw( :DEFAULT :flock);
use CGI::Carp qw(fatalsToBrowser); 

use constant UPLOAD_DIR        => "files_uploaded/";
use constant BUFFER_SIZE      => 16_384;    # Amount of upload file to
+ read at one time
use constant MAX_OPEN_TRIES    => 100;

$CGI::DISABLE_UPLOADS      = 0;
$CGI::POST_MAX             = -1;

my $grab_files    = CGI->new;            
my $donepage    = "upload_complete.pl";

UPLOAD_FILE:
{
    for my $file_num (1..5) {
        my $file = $grab_files->param("file$file_num") or next UPLOAD_
+FILE;
       my $filename = $grab_files->param("file$file_num");
       my ($base,$path,$type)=@_;
       my $file_handle = $grab_files->upload("file$file_num");
        my $format = $grab_files->uploadInfo($file)->{'Content-Type'};
        my $buffer = "";

        if ($file) {

               $filename =~ s/</&lt;/g;
            $filename =~ s/>/&gt;/g;  
          
            fileparse_set_fstype("MSWin32");
            ($base,$path,$type) = fileparse($filename,'\..*');
            my $type = lc $type;
            my $uploadedfile = $base . $type;

            $uploadedfile =~ s/[^\w.-]/_/g;
            if ( $uploadedfile =~ /^(\w[\w.-]*)/ ) {
               $uploadedfile = $1;
            } else {
               error( $grab_files, "Invalid file name; files must star
+t with a letter or number." );
            }

            # This will create the new file
           until ( sysopen OUTFILE, UPLOAD_DIR . $uploadedfile, O_RDWR
+|O_CREAT|O_EXCL ) {
               $uploadedfile =~ s/(\d*)(\.\w+)$/($1||0) + 1 . $2/e;
               $1 >= MAX_OPEN_TRIES and error( $grab_files, "Unable to
+ save your file. File 1" );
           }

            while ( read($file_handle,$buffer,BUFFER_SIZE) ) { 
                print OUTFILE $buffer; 
            }
            close OUTFILE;
        }
    }
}

# Send them to the confirmation page.
print $grab_files->redirect($donepage);
