It looks like in the field where it asked for the session variable name it you put: $_SESSION["remote"]
but it was expecting just the variable name: remote
That caused the code to be wrong and it wrote:
if (((sizeof($this->Items) >= 1)) && ((isset($_SESSION['$_SESSION[\"remote\"]'])))) {
it should just be:
if (((sizeof($this->Items) >= 1)) && ((isset($_SESSION['remote'])))) {
