Alrighty Then...
Typically a subform is setup in a many to one relationship with the main form. It almost sound like in your case, you have a one to one relationship. If this is the case, your could try adding an On_Change event to the control on the main form, and then using that to change the control on the sub form.
Code:
Me.frmSubForm.txtSex = Me.txtSex
I would think that should work.
