Create a paragraph number for many chapters in Book

Hi @fierce_guide0798:

I see you are new here—welcome. 

Can you please clarify your workflow?

• Are you working with one InDesign document, or with multiple InDesign .indd files, pulled together into an InDesign book file (.indb)?
• Are you asking to how increment the chapter titles by 9 and then by 10s? i.e., 1, 10, 20., 30, 40... etc.

Details help us help you faster, and eliminate guesswork. And that said, before you provide the clarification, I'm going to guess that your best bet is to number these manually because auto-numbers increment by 1s. As a workaround you might hide the undesirable numbers, but that's likely more work than just typing in the numbers.

So does Chapter 3 start at 20? Some other number?

Where is your problem?
