Subforms in navigation form

[Rashid]

How to refer any field of a subform in a navigation form.
Like MynavigationF, MySubform, (Field:StudentID).

Not sure if the navigation part makes a difference. I know they are not like standard forms.

Forms: Refer to Form and Subform properties and controls

The navigation form is the parent form. Your form is in the subform control. If that form has a subform, that is a third level if you are referencing the subform's subform externally. If you are referencing the sub-sub form from the subform, then just use
Me.sfrm.Form!StudentID

I've attached a helpful reference guide.
