populate data in subsubform based on what's selected in subform (d

[Jeff]

Hi,
I have a subform (data sheet). I need to populate data to a
sub-subform. Is that possible?

e.g. In my subform, I have a field called entryNumber (hidden column).
Depends on which record is clicked, I need to:

1) find out the entryNumber for that record.
2) requery sub-subform using that entrynumber.
3) display all the records that met that criteria.


Thanks.
