I am working on my register page.

I start the session at the top of my php file:

Code:
<?php

	// Lets start the session
	session_start();
After form/data validation I create some session variables ($username comes from the HTML textbox and $insertedId comes from a select statement):

Code:
			// Lets set a few session variables
			$_SESSION['userName'] = $username;
			$_SESSION['userId'] = $insertedId;
Once sesssion variables are set I change locations to another php file:

Code:
			// Lets get out of here ...
		 	header("Location: home.php");


now, I am in home.php and I try to print my session variables:

Code:
<?php  

			echo "userName=". $_SESSION['userName'];
			echo "userId=". $_SESSION['userId'];

?>


This is the error message I get:

Notice: Undefined variable: _SESSION in C:\wamp\www\TheLastPick\home.php on line 45
userName=
Notice: Undefined variable: _SESSION in C:\wamp\www\TheLastPick\home.php on line 46
userId=



Any idea why my session variables aren't accessible in home.php?

Many thanks for any help.
