I have an access form, "frmCompetition" with a subform, "sfrmDogBrace." This is a database for field trials for bird dogs. I would like to filter the contents of the subform based on selections I make in 3 separate comboboxes in the main form. Any advice? I've tried makeing the underlying query of the subform reference the contents of the 3 comboboxes as criteria. No luck. Is there some vba code I could use? My comboboxes are cboyear, cboday, and cbo brace.
