That is not what I was asking, I’m asking if this “Page 1, Back, Page 2, Back, …” document is going to be saved to DOCX or PDF format?
Again, can you please send us your DOTX file and the multi-page output file that you generate?
As mentioned before, the problem is how to find where the automatic page break will occur. You can think of this like following, let’s say you have a website, an HTML, and you want to find out what content is on what page when you print it, that is the exact scenario you have.
You see, Word documents themselves do not have a page concept, they are of a flow document type, the page concept is specific to a Word application(s) that is rendering it. The flow document types (DOC, DOCX, RTF, HTML, etc. formats) define content in a flow-able manner and when you open these documents in some application it must paginate and render its content (there can actually be differences in rendering between different applications).
On the other hand, the fixed document types (like PDF, XPS, etc. formats) do have a page concept because the content is fixed, it is defined on which page and on which page’s location some specific content will be rendered. This is why this document is rendered in any application the same.
So in short, the problem is if/how we could detect the page breaks in your “multi-page output of ‘front’ pages” document. For me to answer that I will need to investigate your document.
