HELP - varible not passing from form

G'day - I've just installed PhP 4.3.8 for win - running Win2000. Php seems to running ok but when I attempt to use "<form method="get" action="http://localhost/filename"> What is your name: <input type="text" name="Name"> <input type="submit"> The info I type into the text box on the htm page gets passed on the url to the php page, but I get a "Variable Undefined" error in body of php page. There's no problem with case in variable name. Have tried everything I know (which is not much) Any help greatly appreciated.
