Looking at the code on the page, i found that the recordsets where not created properly:
On the Order History page, the problem is the WADAOrders recordset.
the select statement was limiting the columns returned:
SELECT OrderUserID FROM Orders
It should be:
SELECT * FROM Orders
On the order details, User ID Session Variable was being compared to the Order ID column in the Where statement:
AND Orders.OrderID = paramUID
it should be the OrderUserID column
AND Orders.OrderUserID = paramUID
