show content in a dir script

hejsa
kan ikke få dette script til at virke, nogen der kan se hva der er galt?
dir som den skal bruge ligger i root

<?php
//define the path as relative
$path = "/download";
//using the opendir function
$dir_handle = @opendir($path) or die("Sorry we were Unable
to open $path");
echo "Listing of $path<BR>";
//running the while loop
while ($file = readdir($dir_handle)) {
echo "<a href=$file>$file</a><br>";
}
//closing the directory
closedir($dir_handle);
?>
