InfoPath Dev

I have added an OnAfterChange event (using Autopopulation example from Chpt 3 of Developing Solutions with MS IP by Halstead) and the event does not fire. Selecting the OnAfterEvent and clicking edit shows me the code in VS.net, but it never runs. Any idea what I have to do to get this to work?
TIA

Per the SDK, OnAfterChange occurs after changes to a form's underlying XML document have been accepted and after the OnValidate event has occurred.

It will not get triggered unless a value in the field is being changed. If the user merely tabs into the field and tabs out of the field without changing a value in the field, the event will never get triggered.

While in the Form Preview mode, I have been typing into the field and then leaving the field, but the event still does not change

Can you post your code in that event?
