eCart Redirect IsEmpty

We have two sections on our website.

1) A public section where people add to basket and proceed to payment
2) A private section where people return (login) to complete a previous order

We need to ensure that if the customer is returning to a previous order that the IsEmpty Redirect, or any Redirect for that matter, is pointing to the correct place.

At the moment, it's set to:

<?php
if ($eCartSMC->IsEmpty())     {
  $eCartSMC->redirStr = "health-screening-form.php?tab6=1";
  $eCartSMC->cartAction = "RedirectIfEmpty";
}
?>

But health-screening-form.php is for new customers. Our page for logged in customers is view_order.php.
Is this going to cause us problems?

Thank you.

You could redirect them to the view_order.php page and have a redirect on that page if they aren't logged in to health-screening-form.php?tab6=1. That way if they are logged in they see the first page and they get the health form if they aren't.
