I created customized headings for a document. I'm trying to follow a format from an older document. The first sections are 1.0, 2.0, 3.0. Subsections are 1.01, 1.02....., 2.01, 2.02, and so on.

I am able to get MS Word to change the last numeral in each subsection. When switching from Section 1.0 to Section 2.0, I have to create a new heading. Now, the table of contents (TOC) does not recognize my custom headings. Plus, I cannot rename the custom headings to a name already set aside for the default styles. Seems as though the TOC only picks up the styles named Heading 1, Heading 2, etc.

Any ideas for a fix that keeps my numbering style and allows TOC updates?

Thank you.

You might get better results if you used the Organiser to import the relevant Styles from the older document. See Developer|Document Template>Templates>Organiser

Thank you for the replies.

I figured it out myself. To cure the 1.01 and 2.01 subheadings, choose "Level 1" in "include list level". Then both numbers change at the same time.

Choose "Define New List Style" in Paragraphns on toolbar then "Format" then "Numbering" which opens a Modify Multilevel List window. From there you can choose to include the list level.
