The problem seems to be with this section:
$_SESSION[$EmailRef."_Status"] = $GLOBALS[$EmailRef."_Status"];
$_SESSION[$EmailRef."_Index"] = $GLOBALS[$EmailRef."_Index"];
$_SESSION[$EmailRef."_From"] = $GLOBALS[$EmailRef."_From"];
$_SESSION[$EmailRef."_To"] = $GLOBALS[$EmailRef."_To"];
$_SESSION[$EmailRef."_Subject"] = $GLOBALS[$EmailRef."_Subject"];
$_SESSION[$EmailRef."_Body"] = $GLOBALS[$EmailRef."_Body"];
$_SESSION[$EmailRef."_Header"] = $GLOBALS[$EmailRef."_Header"];
$_SESSION[$EmailRef."_Log"] = $GLOBALS[$EmailRef."_Log"];
Errors are: Notice: Undefined index: WAUE_confirm_1_Status in (path to confirm.php), and repeated for each variable. Session Values are populating correctly. Output in PM section.
