Problema con $_FILES

[paloclanweb]

Hola tengo el siguiente script para hacer upload . El fichero deseado sube perfectamente pero no logro imprimir el nombre del fichero .. a que se debera?
gracias de antemano
<?php
$target_path = "pic/";

$target_path = $target_path . basename( $_FILES['Filedata']['name']);

if(move_uploaded_file($_FILES['Filedata']['tmp_name'], $target_path)) {


echo "The file ". basename( $_FILES['Filedata']['name']).
" has been uploaded";
} else{
echo "There was an error uploading the file, please try again!";
}

?>
