Yes, the nested recordset tutorial will help, it doesn't matter that you don't have data bridge, the concept is still the same.
basically you are just creating a master detail page set.
the master page shows the orders, with a link to the order details page, the link passes the orderID as a URL variable:
orderdetails.php?OrderID=12
on the order details page, you create a recordset that filters the OrderID column by the passed URL variable.
