This simple technique makes quick work of a single-level numbered list and accommodates multiple lists within the same document. However, it doesn't work with multilevel lists. If you must work with an existing document, modify the heading style as shown above. Then, select each heading and apply the heading style that you modified by adding a numbering scheme. As I mentioned, this isn't possible if the existing document already employs the heading style. But if you face numbering headings in a document, you know you've got the request covered—and you won't lose a minute's composure. Just tell them, "Yes, I can do that."
That’s not exactly correct. It prints correctly on one machine but not others. So it’s not the difference between the screen version and the print version. In most cases, it prints as it looks on the screen. Read the article you are commenting on for the reasons. From my experience, the most common reason is due to the different fonts installed on the machines. I once received a document to print and the layout was all wrong. I installed the missing fonts and it printed correctly.
So, to create multi-level headings, you need to use the Level option just to the right of the List drop-down box. My second- and third-level headings use the same list as the first-level headings (this is necessary), except that they are changed to Level 2 and 3, respectively. Then, when numbering the section heading, you can insert the number of the previous-level heading above it. These can be selected using the arrow to the right of the Number field and selecting one of the levels under “Insert Number Placeholder.” So, the text in the Number field for my second-level heading is ^1.^#^t and it is ^1.^2.^#^t for the third-level heading. This presents the multi-level heading with dots between the numbers and a tab between the numbers and the section heading.
In Japanese, Chinese, or Korean versions, by default, Arabic numerals are used for page numbers. However, if you use the Numbering & Section Options command, you can specify the style of numbering, such as Roman numerals, Arabic numerals, Kanji, and so on. The Style option allows you to select the number of digits in the page number, for example, 001 or 0001. Each part of the document that uses a different numbering style is called a section. For more information on sections, see Define section numbering.
