OK... I am using the CGI module for an upload script. However... I need to limit the size of the directory and the size of the file. Can you all possible help?? Here is my code however it doesn't work :( 
#!/usr/bin/perl

alarm(600);
use CGI;
use Fcntl qw( :DEFAULT :flock);
use File::Basename;

use constant UPLOAD_DIR        => "/usr2/home/undernet/losts/public_ht
+ml/playeruploads/";
use constant BUFFER_SIZE    => 16_384;
use constant MAX_FILE_SIZE    => 2 * 1_048_576; # Limit each upload to
+ 10mb
use constant MAX_DIR_SIZE    => 100 * 1_048_576; # Limit total uploads
+ to 500mb
use constant MAX_OPEN_TRIES    => 100;

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

$in = new CGI;

$img1        = $in->param('image');
$action        = $in->param('action');
$imgdir        = '/usr2/home/undernet/losts/public_html/playeruploads'
+;

print "Content-type: text/html\n\n";
&headers;
&body;

if ($action eq "uploadfile") {
    &uploadfile;
} else {
    &displayform;
}

&footer;



sub displayform {
    print << "!!!EOF!!!";
