Find Record In Main Form Based On Selection In Subform

Can someone tell me how I migh find a record in a main form based a a selection in my subform?

I have a Main form called frm_ProductionSchedule.

It contains three subforms:
frm_ProductionSchedule_subform
frm_ProductionSchedule2_subform
frm_ProductionSchedule3_subform


I would like to be able to select a record within any of the subforms and have the main form display it. The main form is linked to a SQL server Table. The subform are based on queries. The unique PK field is a date field called record_date.

I should add that the Link Child/Master fields are blank for all Subforms. Each Subform is linked to a query and displays data for a particular machine (1,2 or 3) AND is updated based on a combo selection of the Production week. The queries for one subform would look something like this:

SELECT dbo_tbl_ProdSchedule.PartType, dbo_tbl_ProdSchedule.PartNumber, dbo_tbl_ProdSchedule.Work_order_no, dbo_tbl_ProdSchedule.FrameType, dbo_tbl_ProdSchedule.FrameNumber, dbo_tbl_ProdSchedule.Shift, dbo_tbl_ProdSchedule.Sch1_date, dbo_tbl_ProdSchedule.Sch1_spins, dbo_tbl_ProdSchedule.Sch1_sheets, dbo_tbl_ProdSchedule.Sch2_spins, dbo_tbl_ProdSchedule.Sch2_sheets, dbo_tbl_ProdSchedule.Sch3_spins, dbo_tbl_ProdSchedule.Sch3_sheets, dbo_tbl_ProdSchedule.Sch4_spins, dbo_tbl_ProdSchedule.Sch4_sheets, dbo_tbl_ProdSchedule.Sch5_spins, dbo_tbl_ProdSchedule.Sch5_sheets, dbo_tbl_ProdSchedule.Sch6_spins, dbo_tbl_ProdSchedule.Sch6_sheets, dbo_tbl_ProdSchedule.Sch7_spins, dbo_tbl_ProdSchedule.Sch7_sheets, dbo_tbl_ProdSchedule.Frames_due_date, dbo_tbl_ProdSchedule.Comments, dbo_tbl_ProdSchedule.Record_date
FROM dbo_tbl_ProdSchedule
WHERE (((dbo_tbl_ProdSchedule.Sch1_date)=[Forms]![frm_ProductionSchedule]![cmbSchDisDate]) AND ((dbo_tbl_ProdSchedule.SpinCoaterNo)=1));

AND WHERE ((dbo_tbl_ProdSchedule.SpinCoaterNo)=2)), etc. Respectively for each subform.

Thanks in Advance!!
