MM_Username Variable

Question

Hi. I hope someone can help as I've been struggling with this
for a few weeks.
On the first php page I have the user register and log in
automatically. On the 2nd php page i want to greet the username but
the MM_Username variable won't appear on the screen. I'm using
Apache2 as the testing server. Where am I going wrong?
Here's the code:-

<?php require_once('Connections/registration.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType,
$theDefinedValue = "", $theNotDefinedValue = "")
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue)
: $theValue;
$theValue = function_exists("mysql_real_escape_string") ?
mysql_real_escape_string($theValue) :
mysql_escape_string($theValue);
switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" :
"NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
