I'm using Word 2013 in Windows 7.

I have a document with a continous section break halfway down the page (required for different margins). The format for the document is set "Different first page"

The footers for the first page say, when I open it "First page footer - Section 1"

What I'm trying to do is change the bottom margin of the first page and not of the second and subsequent pages.

I've tried the following code which gives me an error when run:

    With ActiveDocument
        .Bookmarks("\StartofDoc").Select
    End With
 
With ActiveDocument.Sections(1)
    .Footers(wdHeaderFooterPrimary).Range.PageSetup.BottomMargin = CentimetersToPoints(5)
 End With
I've obviously got the whole thing wrong but my search does not reveal any likely solution. Can anyone help with one, please?
