	session_start();
	$sessionActive  = '<p>Session was STARTED</p>';

	$sessionActive = '<p>Session was PRESENT</p>';

 if (isset($_SESSION) && isset($_POST["name"])) {
	 $_SESSION["name"] = $_POST["name"];
 }

echo '<br /<br />var_dump session:';
	var_dump($_SESSION);

$name = $_SESSION['name'];
echo "Name in session is: " . $name . "<br /><br />";

You can see the changes from your original code (I just pasted that in verbatim in the first revision) in the revision history.

Second revision cleans up some html problems in the form: removed the extra form, and an unmatched , indented, etc...

Third revision changes the post/session related stuff on the form: We make sure the action of the form points to the formHandler.php, and don't bother with dealing with the session at all in the form, as it isn't needed there.

Fourth revision fixes $_POST typo
