Page Numbering

Hi, new to the forum. I hope someone can help me.

So I have a rather large document (Directory) and I need to split the document into 2 as its becoming too large to work on. It is all page numbered using master pages.

The problem I have is starting the numbering in the second doucment following the first document ending. For example.. If I split the document into 2. The first doument ends on page 16. The next document needs to start as page 17. Does anyone know how to do this? I can only think of numbering the second document the same as the first and leaving the pages previous blank until the numbering starts correctly.

I hope this makes sense.

Thanks

Paul
