Access denied when trying to upload document to server

[boilerpowered]

I am currently trying to write a php script that will upload a document from the clients computer to my server. I am getting the following error:
--------------------
Warning: move_uploaded_file(/xampp/htdocs/creative/document_library/test_upload) [function.move-uploaded-file]: failed to open stream: Permission denied in C:\xampp\htdocs\creative\scripts\php\logic\resizejpg.php on line 29



Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move 'C:\xampp\tmp\php403B.tmp' to '/xampp/htdocs/creative/document_library/test_upload' in C:\xampp\htdocs\creative\scripts\php\logic\resizejpg.php on line 29
--------------------

Here is the code I am using:
--------------------
ini_set('memory_limit',33554432*9);
ini_set('post_max_size',33554432*9);
ini_set('upload_max_filesize',33554432*9);
ini_set('max_execution_time',240);
ini_set('max_input_time',240);
$target_path = "/xampp/htdocs/creative/document_library/test_upload";
$target_path = $target_path . basename($_files['userfile']['name']);
$_FILES['uploadfile']['tmp_name'];
echo '<pre>';
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['uploadedfile']['name']).
" has been uploaded";
} else{
echo "There was an error uploading the file, please try again!";
}
move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path);
echo 'Here is some more debugging info:';
print_r($_FILES);
print "</pre>";

Has anyone dealt with this error? If so please help.
