I dont know why I have trouble with this but I always do. Main form is named Add Products and sub-form is named Add Products SubForm
I am trying to disable the control TaxStatus on the subform. I tried the below with no luck.
Forms![Add Products]![Add Products SubForm].Form![TaxStatus].Enabed = False
OK, I changed the form names so that NO spaces are there, i.e. AddProducts and AddProductsSubForm
