found the problem with the hidden fields.. selecting them from the form fields in the dynamic lightning bolt dialog box does not permit them to work as the don't seem to be inserted in the behavior as a "repeating" field as it labels itself after being chosen... choosing the hidden fields from the drop down box lists them as repeating fields and the insert multiple record behavior works.
I hope you guys document this as it can be re-created at will and is very difficult to find.
thanks for the great support and attention,
tony
