I've set up heading styles as:
1.1
1.2
1.3
2.1
2.2
2.3

However, Word 2007 is putting the section number first instead of the
chapter number, e.g.,
1.1
2.1
3.1
1.2
2.2
3.2

I've tried deleting and re-creating the numbering information in the heading
styles to no avail. How do I get Word to number the headings correctly?
