Multitable Dataset Windows form

Question

I have been troubleshooting this Walkthrough on the MSDN about saving data to a database with multi table dataset.  The save doesn't actually commit data to the database abd no error is received.  I have ensured that my test project is EXACTLY like the walkthrough.  I am wondering if the walkthrough is missing something.

Can someone go through this and tell me what they think?  It doesn't take very long.
