$max_allowed_file_size = "100"; // this is size in KB
list($name_of_uploaded_file, $type_of_uploaded_file, $size_of_uploaded_file) = GetUploadedFileInfo();

}
?>

doesn't add the file as attachment I just get the name of the file as its in a form element
the loop for getting the form elements work and I get the mail but I do not get the file uploaded to the uploaded folder as I was checking the folder using filezilla during testing this script
