Removing HeaderFooters with VBA

[IanDB]

example
Document with 5 sections
Different headers added thus:

ActiveDocument.Sections(1).Headers (wdHeaderFooterPrimary).LinkToPrevious = False
ActiveDocument.Sections(1).Headers(wdHeaderFooterPrimary).PageNumbers.Add.Alignment = wdAlignPageNumberCenter

etc thru all sections

Now need to remove all headers from section 3 only.
(There's no ActiveDocument.Sections(1).Headers(wdHeaderFooterPrimary).PageNumbers.delete

Any help appreciated
