To make sure I understand what you mean:
Do you want to start indexing from a certain page in your document (ignoring the pages before that)?
Do you want to place your index text at a specific page in your document?
I would like to index the document beginning at the first page, and ending at the last page. I have already created my topic list. All that remains now is to flow the text from the topic list to the index pages. That is the step for which I cannot find instructions. Any help would be appreciated.
Did you find success with Eric's suggestion? Let us know if you need any more help.
