Thank you Wayne-I-M for responding

FYI: I'm using Access 2007, and the combo boxes are unbound.  The fields i'm
using are not primary fields, and i use the Distinct key word for populating
the combo boxes, which worked in the cascading listbox example.

OK, Consider this, i have a table with over 100K records, about 50 fields.
The class field has 210 items that repeat through out the records in this
table.  I want to chose this class field as an example, then select one item
in the drop-down combo box, and filter all records based on the combo box
selection.  I also have 3 cascading combo boxes.

I hope the combo box works like the list box,  As i previously mentioned, i
have been able to get the 3 cascading list boxes to work with 3 different
queries.  The Second list box query selects from the first list box query...

I think the problem i'm having is passing the value from the combo box
selection to the query.

Thanks for your help

Best regards,
