Connecting To Data In Objects?

I am currently working my way through a MSDN Walkthrough titled Connecting to Data in Objects, the link for this is

[URL]

I have worked up to the section Adding Code to Load Data into the Customer and Order Objects section with no problems, but the Public Class Form 1 code is throwing an error hilighted in italics as per below,

Private Sub LoadOrders(ByRef currentCustomer As Customer) Dim orderData As NorthwindDataSet.OrdersDataTable = _ OrdersTableAdapter1.GetDataByCustomerID(currentCustomer.CustomerID)

This is the Description returned from the error list,

Error 1
Description - Value of type 'ObjectBindingWalkthrough.NorthwindDataSet.OrdersRow' cannot be converted to 'ObjectBindingWalkthrough.NorthwindDataSet.OrdersDataTable'.

[code]....

In the walkthrough I also came across a problem under the heading Modifying the Query on the OrdersTableAdapter to Return Only Orders for the Desired Customer This SQL throws an error,

SELECT OrderID, CustomerID, EmployeeID, OrderDate,
RequiredDate, ShippedDate, ShipVia, Freight,

[code]....

But the following edit to the Where clause gets around the error, the @ symbol is removed,WHERE CustomerID = CustomerIDcould this be causing the problems I am having described above, or is this just an error.
