I have 1.2.1.1 then 1.2.1.2 and then 1.2.1.3 and so on. I added new stuff in between 1.2.1.1 and 1.2.1.2 so I renamed 1.2.1.2 to 1.2.1.5 and so on

unless you are using Word 2010 Heading styles, then these new entries will not be automatically added to the Table of Contents...
</div>


<div>
How do I use Word 2010 Heading styles? That is, what do I have to do so that the document sees these news ones as part of the Contents?
</div>


<div>
are you generating the table of contents automatically?<br />
<br />
are you modifying an existing document created by another person or did you create the original document?
</div>


<div>
This is an existing document that I am modifying. I am not sure what you mean by generating the table of contents automatically. I right-click on the Table of Contents, when the &quot;Update Table of Contents&quot; window pops up, I check on &quot;Update entire table&quot; and click on OK. Typically, if any new items have been added in the document, they get added to the document automatically.

<div>
That did the trick. You're the man.

I have Contents in a document. I have 1.2.1.1 then 1.2.1.2 and then 1.2.1.3 and so on. I added new stuff in between 1.2.1.1 and 1.2.1.2 so I renamed 1.2.1.2 to 1.2.1.5 and so on. However, when I right-click on Contents then Update Field and then Update entire table, it doesn't update the contents to include the new 1.2.1.2 etc. I am using MS Word 2010. In the picture below, it doesn't include <br />
1.2.1.2 X<br />
1.2.1.3 Y<br />
1.2.1.4 Z <br />
in the Contents. Any help would be appreciated.<br />

Adding to contents in a document

Microsoft Word is a commercial document editing program that is part of the Microsoft Office suite. It features numerous text-editing tools for creating richly formatted documents, along with tools for the use of macros in Word documents. Word's native file formats are denoted either by a .doc or .docx file extension. Plugins permitting the Windows versions of Word to read and write formats it does not natively support, such as the OpenDocument format (ODF) are available. Word can import and display images in common bitmap formats such as JPG and GIF. It can also be used to create and display simple line-art.
