InfoPath Dev

Hi, I don't know hot to get values from an RepeaterTable in InfoPath, I think it is:

XPathNavigator root = MainDataSource.CreateNavigator();
XPathNodeIterator nodes =
   root.Select("/my:myFields/my:group1/my:field1", NamespaceManager);

while (nodes.MoveNext())
{
    message += nodes.Current.Value + System.Environment.NewLine;
}
MessageBox.Show(message);

but, don't works!

somebody help me, please!

Are you getting an error message?  I'm not too familiar with the IP07 OM, but this looks sane.
