To start, temporarily turn on the viewing of hidden formatting symbols by clicking the 'Show/Hide' symbol on the 'Home' tab in the 'Paragraph' box - this will enable you to see the Section Breaks between sections of your document. To use different page numbering schemes in different sections of your Word document, there are two tricks: 1) you must include a 'Section Break - Next page' between each section of your document where the numbering will change, and 2) you must 'unlink' each section's footer from the one before it.
