How do I access the recordset of a SUBform. I know how to clone the set of a form, but this doesn't work for subforms.

All Versions: Let me guess, you tried: forms!myform!MySubForm.RecordsetClone

This will always fail as MySubForm points to a control on the form, you need to access it's Form propery, thus:

forms!myform!MySubForm.Form.RecordsetClone

Should work OK.
