An InDesign document can only have one chapter, and these chapters are typically combined in an InDesign book. To insert a chapter number, create a text frame where you want the chapter number to appear on either a document or master page. Click on the "Type" menu, then "Text Variables," "Insert Text Variable" and then "Chapter Number." Update the chapter number if necessary to keep your chapter numbers consecutive by clicking on "Numbering & Section Options" in the Layout menu.
Thanks David for posting this for me. And thanks for sending me the .inx fie. I had a complete memory lapse on how to make a number list like that and was uber-cofused. If it was written about before I couldn’t find it on the search function for the site. And even if it is over a year old it’s still good info. It is in the Mailbag section so it really was just an answer to an email and generoulsy posted.

A defined list can be interrupted by other paragraphs and lists, and can span different stories and different documents in a book. For example, use defined lists to create a multi-level outline, or to create a running list of numbered table names throughout your document. You can also define lists for separately numbered or bulleted items that are mixed together. For example, in a list of questions and answers, define one list for numbering the questions and another for numbering the answers.

Two things to keep in mind regarding numbering across multiple frames: First, you have to set up a List, as discussed in this post. Second, fi you have more than one unthreaded text frame on the same page, the numbering can get wonky because the numbering is based on the order you created the text frames. Cut and paste a frame and the number updates.
If the list you want is as simple as "1", "2", "3", you'll appreciate how easy it is to apply this type of numbering in legal documents. Simple numbered lists are different in Word 2000 than they were in Word 97. In Word 2000, the default for even the most basic list is multi-level. For example, if you number an item and press Enter and then press the TAB key, Word automatically formats this number as the second level in an outline numbered list format. Single and multi-level numbering are explained later in this chapter.
One solution is to format the heading with the style and follow it with a hidden paragraph mark. You should format the text in the next paragraph with a style that is not included in the Table of Contents. A hidden paragraph mark keeps the text together on one line when it is printed, even though it is actually two separate paragraphs. The Table of Contents command picks up only those paragraphs with heading styles and places them into the Table of Contents.
There’s an old Steve Martin joke about how to make a million dollars which starts, “First, get a million dollars…” That’s the key to this trick, too: First, get a bunch of numbers. Here’s a file with 1,197 numbers in it. Now import or paste those numbers into a thread so that the numbers appear in the right place. If you need two matching numbers, just import it twice.

I’m unable to access Numbering & Section Options from the Master page (it’s greyed out). I had already manually ‘told’ all the files in my Book where to start, using the Numbering & Section Options from the Layout toolbar (I didn’t know it could be done through the Pages menu). They still show up in the Book listing as starting from page 1, though. I had to juggle between the Document Setup on the File toolbar and the …Options from Layout to get the page numbers to come right. As I have a lot of illustrations throughout the Book, I’d like to have the correct page numbers come up so I can easily find and acknowledge them.

The next step is to create the simple Excel workbook that contains the ticket numbers. Open a blank Excel sheet. Using Figure B as a guide, create the ticket numbering sheet and save it, making sure to note the new workbook's name and location. As we discussed earlier, the Excel workbook stores the ticket numbers. In this example, we'll create 11 tickets numbered 100 through 110. You'll need to update the ticket values for each merge.
