MS Access 2007/2003 - Referencing a control on a sub form, from the parent form

So if I want to reference a control (like a text box开发者_开发问答) on a sub form, from the CBF of the parent form, how should I do this?

me.SubForm.SubControl  

Gives me an error.

Me.SubformControlName.Form.SomeControl

Be sure to use the name of the subform control, not the form contained - they are often the same, but not always.
