To use a "normal" Table of Contents that generates the page numbers itself, the numbering and formatting comes from the settings in the "Format Page Number" dialog.
So to do it this way, the page numbers have to start at 1, not at 4.
In order to achieve that, you need to ensure that there is a section break (Layout Tab->Page Setup group->Breaks dropdown) before your Introduction.
Then you can go into the Header/Footer for the section, choose Design Tab->Header&Footer group->Page Number dropdown->Format Page Numbers..., then set Page Numbering to Start At 1.
You can then change your page numbering field from
{ ={PAGE}-3}
back to
{ PAGE }
However, if you also need another numbering sequence (as in the question you reference), you can calculate that one from { PAGE }, e.g. if you need Roman numbering on page "1" to start at IV, you can use
{ ={ PAGE }+3 \*ROMAN }
If you are also using { NUMPAGES }
, e.g. in page numbering such as
Page n of m
then you may need to use a calculation to modify the value of NUMPAGES, e.g.
{ ={ NUMPAGES }+3 }
but I cannot tell from the question as it stands.
My question is not the format, it is about the numerical value. – Dirk Horsten – 2016-05-24T05:51:54.550
