How do I turn off the page numbering in a new Section 2, while keeping the previous page numbering in the old Section 1 ?

(I search this forum to find the trick to create a new Section using :
Selection.InsertBreak Type:=wdSectionBreakNextPage

but I can't access the header in my Section 2 with :

With Selection.Sections(1).Headers(1).PageNumbers
.NumberStyle = wdPageNumberStyleArabic
:
:
End With
)

Thanks !
