I am working with a document I did not create and it is a stand-alone chapter of a larger document. The TOC and all pagination, including the front matter footer, starts with a 12. I need it to start with 13. Looking through all the custom styles, I have found that the Heading 7 style is where it shows that the numbering should start at 12. I have not found a way to modify that to be 13. When I click on Modify Style, then Format Numbering, it does not give me an option to change the start number. Is there a way to do this? Thanks in advance.

In Word 2010 (and 2007), you can't modify outline numbering via the Modify Style dialog box. Instead, do the following: Place the insertion point in the first level 1 paragraph of the document (with heading numbering, this implies the first Heading 1 paragraph). Click Home tab | Multilevel List | Define New Multilevel List (yes, it doesn't make sense that the option is called "define new"). Then make the desired changes to the appropriate numbering levels.
