I have a subform which has cascading combo boxes to select Contractor equipment type, manufacturer, model no, etc.  When I add the 2nd, 3rd... records, the equipment type is being duplicated from the first record.  The view of the subform is datasheet.  How can I fix it so the equipment type is not automatically duplicate?  If I select another type of equipment on the 2nd record, it changes the 1st one as well and so forth,
Thanks
