What I want to achieve is display of page numbers in my tables of contents. For example, first section of chapter 2 starts at p. 54 in the whole document. However, in both tables of contents (the one of the whole thesis and the one of chapter 2), it is listed as in p. 2 because it is in p. 2 of the individual chapter 2.
Another remark regarding the INCLUDETEXT method: when there are more than 12 documents, INCLUDETEXT fails at the 12th document with the message: "Fields Are Nested Too Deeply"...
