Hvorfor virker upload script ikke?

Hey:)

Jeg har oprettet dette script:

print"
<form action=\"indsend_rekord.php\" method=\"post\" enctype=\"multipart/form-data\">
  <input type=\"file\" name=\"upfil\">
  <input type=\"submit\" name=\"upload\" value=\"upload\">
</form>
";

} else {
}


$konfiguration["upload_bibliotek"] = "/billeder";
$konfiguration["max_stoerrelse"] = "50";

list($major, $minor, $rev) = explode(".", phpversion());



if($minor < 1) {
  $_FILES = $HTTP_POST_FILES;
  $_POST = $HTTP_POST_VARS;
  $_SERVER = $HTTP_SERVER_VARS;
}

$fra = $_FILES["upfil"]["tmp_name"];
$til = $konfiguration["upload_bibliotek"] . "/" . $_FILES["upfil"]["name"];


$fil_stoerrelse = filesize($fra)/1024;
if($fil_stoerrelse > $konfiguration["max_stoerrelse"]) {
  die("Desværre - filen er for stor. Vi accepterer kun " .
      $konfiguration["max_stoerrelse"] . "kb, og din fil fylder " .
      ceil($fil_stoerrelse, 1) . " kb");
}


if(function_exists("move_uploaded_file")) {
  move_uploaded_file($fra, $til); <<< dette er linie 265
} else {
  copy($fra, $til);
}

Ud fra denne artikel:
http://www.webcafe.dk/artikler/php/upload/

Men når jeg prøver at uploade får jeg flg udmelding:

Warning: move_uploaded_file(/billeder/gb.jpg): failed to open stream: Ingen sådan fil eller filkatalog in /var/www/html/n-gamez/hi_score/indsend_rekord.php on line 265

Warning: move_uploaded_file(): Unable to move '/tmp/phpAG5tOZ' to '/billeder/gb.jpg' in /var/www/html/n-gamez/hi_score/indsend_rekord.php on line 265

hva er der galt?
