restart page numbering for an inserted document

Hi,

I am trying to insert word documents, and then add a section to restart page numbering for each newly inserted document.  However, the page numbers do not restart, and the first document has no page numbers at all:

 m_WordApp.ActiveDocument.Repaginate()
                'If Not fileArray.Contains(filepath) Then
                Dim oSection = m_WordApp.ActiveDocument.Sections.Add()

                oSection.PageSetup.DifferentFirstPageHeaderFooter = False
                oSection.Footers(WdHeaderFooterIndex.wdHeaderFooterPrimary).LinkToPrevious = False
                oSection.Footers(WdHeaderFooterIndex.wdHeaderFooterPrimary).PageNumbers.Add(WdPageNumberAlignment.wdAlignPageNumberCenter)

               
                m_WordApp.Selection.InsertFile(filepath, ConfirmConversions:=False, Range:="", Link:=False, Attachment:=False)
                'm_WordApp.Selection.InsertParagraphAfter()
                m_WordApp.ActiveDocument.Repaginate()
                m_WordApp.Selection.InsertBreak(Type:=WdBreakType.wdPageBreak)
                m_WordApp.Selection.EndKey(Unit:=6)
                m_WordApp.Selection.Collapse(Direction:=WdCollapseDirection.wdCollapseEnd)

The initial formatting is as follows:

 Dim oSection = paragraph1.Range.Sections.Add()
                oSection.Footers(1).LinkToPrevious = False
                '               objDoc.Sections(1).Footers(1).PageNumbers.Add(wdAlignPageNumberCenter)
                oSection.Footers(WdHeaderFooterIndex.wdHeaderFooterPrimary).PageNumbers.Add(WdPageNumberAlignment.wdAlignPageNumberCenter)

Any help would be greatly appreciated
