Livecycle Designer form connected to database - button to advance to next record does not work

[Mike22Doyle]

I have a liecycle designer form that is connected to a query in an MS Access 2010 database.  I have placed a button on the form to advance to the next record.  It doesn't appear to be doing that. The form was created using Livecycle Designer ES4. When I click on the button nothing happens.  I realize it might be something as simple as a refresh, and if that's so, please give me a hint as to how to do that.

Thanks.

here is the header in the XML of the form.
