One of the last things we need to do is our Table of Contents. We did this earlier, where we had different page numbering. So, all we need to do now is, because we've redefined all our Styles, and we're doing it all proper now, if we go to 'Layout'-- I've got my cursor flashing in here, first of all go to 'Layout', let's go to 'Update Table of Contents', and I'm going to click 'OK'. There's some spaces left in the front of this when I was messing around with it before, yours should be fine. So it's updated to the correct numbers. One thing I also did was I went in and adjusted the font from Medium to Light because I just liked it. I did that in between tutorials.

Warning  Making even minor changes to an outline numbering scheme won't necessarily change the initial position you've selected in the gallery, but rather may create a new gallery position, overwriting an existing one. Because of this problem, attaching numbering to styles is strongly recommended. This is covered in greater detail later in this chapter and in the chapter on Styles.
You can add a chapter number variable to your document. Like page numbers, chapter numbers can be updated automatically and formatted and styled as text. A chapter number variable is commonly used in documents that are part of a book. A document can have only one chapter number assigned to it; if you want to divide a single document into chapters, you can create sections instead.
Changing the numbering display affects how pages are indicated in the InDesign document, as in the Pages panel and in the page box at the bottom of a document window. The numbering display also affects how you specify page ranges when printing and exporting the document. However, the numbering display does not change the appearance of page numbers on document pages. numbering in indesign
