I have a simple form:

<form action="addUser.php" method="post">
  Enter Username:
  <input type="text" name="userName"><br><br>
  <input type="submit" value="Submit">

Submits to addUser.php:

echo $HTTP_SERVER_VARS['userName'];

Returns this error in my browser:

Notice: Undefined index: userName in E:\Inetpub\wwwroot\Test\addUser.php on
line 11

Is there a setting in my php.ini file I need to change? register_globals is
off, as that seems to be the preferred method now. But that's my issue,
trying to access this external variable. $_REQUEST doesn't work. $_POST
doesn't either. I have other scripts that it's working in, but I may not
know what I'm saying here.

PHP 4.2.3 on IIS (personal web server or whatever it's called) on WinXP Pro.

Thanks for any help you can give.
