Insert data from a datasheet on a subform into a table

I've seen other questions similar to this asked on EE, but none seem to fit the bill.

I have a form with a unbound subform. The subform is in datasheet view.  I would like to be able to loop through all the data on the subform after the users enters it and insert that into a table.

Not sure how to loop through the fields on a subform in datasheet view.

Suggestions?

Thanks,
Tom
