In MSOffice 2003 Insert Menu,
Reference
Indexes and Tables, click on "Table of Contents" tab,
Make sure that Build Table of contents from: "Styles" is checked. Click on
"Options" . Number your heading styles in the order you want them to appear
first. (i.e. Heading 1 TOC Level: 1) remove any other 1, 2, and 3 etc. from
the TOC levels window box that you are not using. The default is up to 3
levels, if you need more than that on the Table of Contents tab you have the
option to change the "show Levels", etc.
