He,

Normally I use LaTeX but for the ocation I have to use MS Word. Now I like to make a document that is built up from different subfiles.
This is because I have to make several document that are more or less the same only a view chapters will be different. and the mean part of the document will chance in time, for all the documents.

What I normally do in Latex is including the subfiles in to the mean file.

eq

project1
include introduction
include task
include results a
include conclusion a

project 2
include introduction
include task
include results b
include conclusion b

etc

introduction, task, results and conclusion are separate files. Project is the mean file but that has the overall lay out title page and a short description of the complete articular.

And please don't come with a copy/past solution it is a 100 page report.
