Copy/paste fields in a form

[NewtoAccess]

I have a MAINFORM with a Subform1 which has another subform2.

I want to copy the 'PORT_ID' field from subform2 and paste it to MAINFORM field called 'PORTA'.

I was thinking of having a button in subform2 which would copy and paste all at once.

To Reference the Field in the Sub-Sub-Form from the Main Form:

Me![PORTA] = Forms!MAINFORM!Subform1.Form!Subform2.Form![PORT_ID]

Thank you for the reply!
Comand works exactly as expected when I add the button to the 'MAINFORM'.
But I would like the button placed in Subform2 and have it work the same way.
Possible?

Forms!MAINFORM![PORTA] = Me![PORT_ID]
                OR
Me.Parent.Parent![PORTA] = Me![PORT_ID]
