Use Section Breaks to Allow Multiple Numbering Schemes
Applies to Word 2007, 2010 and 2013 for Windows.
Using sections in your document allows for you to have seperate page numbering schemes, all in the same document. This is useful when you want your front matter to have roman numerals for page numbers, and your main document to have numbers starting from one. To create a new section, place your cursor at the very end of the previous section. Go the Page Layout tab, and in the Page Setup group click on Breaks, then select your preffered type of section break. Usually "Next Page" or "Odd Page" would be appropriate. Use odd page if you would like the next section to start on the right page when your report is opened.
Once you have set up different sections, you can define different numbering styles. If you haven't already, insert page numbers by going to the Insert tab and clicking on page number in the Header & Footer group and selecting the appropriate option. Then, within each section define the proper number format by clicking on Page Number in the Header & Footer group of the Insert tab, and then click on format page numbers, where you can change the number format. You can also choose if you would like for the numbering to continue from the previous section, or start from a number you specify.
