Can't get $_GET to work

Hi Everyone, I'm probably being a bit thick here, but I can't get hold of $_GET or $_POST variables. I've set up 2 files as simply as I can, but no joy. File a.php ---------- <html> <head><title></title></head> <body> name: <form action="b.php" method="get"> <input type="text" name="Name"><br> <input type="submit" value="send"> </form> </body> </html> ----------- produces http://127.0.0.1/b.php?name=fred file b.php --------- <html> <head><title></title></head> <body> Name: <?php echo $_GET['name'] ?> <br> </body> </html> --------- prints Name: and nothing else What *am* I doing wrong? Cheers, Ian
