The Table of Contents (TOC) compiles section titles, headings, and subheadings appearing throughout the report; the TOC must record these headings as they appear in the report itself.
Use simple indentations to indicate subheadings; you will thus avoid any kind of spacing or tabbing problems. To format leader dots properly, use tab options (simply hitting the period key and space bar will not align dots or page numbers correctly). (I advise using styles, which have been preformatted to fit these guidelines. Each time you add a new heading or subheading, each will automatically be added to the Table of Contents, including the page numbers. Though using the styles feature will help insure that your report is correctly formatted, you should still check over your work to make sure that it meets all of the report requirements.)
Begin numbering pages of the report here, starting with ii. (See above concerning Title Page and Transmittal Letter.)
