Follow the steps below...
1. From your Table of Contents page go to Header/Footer View
2. Click to go into the footer
3. From your Header/Footer tool bar, click "Format Page Number" icon (you can see what each icon does what by hovering your mouse over each)
4. Where it says "Number format:" click the arrow and select the lower case roman numerals (standard for TOC page numbering)
5. At the bottom of that window where it says "Start at", click the arrows to start at one (i)
6. Click the "Insert Page Number" icon in the header/footer toolbar. Your page number will appear. Center it if that's where you want the number
7. Click "OK".
That takes care of the TOC. Now for the rest of the document and a change in page numbering:
8. At the last page of your Table of Contents, remove the page break if you have one. (don't worry)
9. From the "Insert" dropdown menu, click "Break" and then "next page". That will insert a Section Break. You need this in order to have alternate page numbering (roman numerals in the first section, and arabic in the second section)
10. Get into Header/Footer view.
11. Click to go to the Footer
12. In the Footer of this section you will see the words "Same as Previous". You will need to change that because you are changing your page numbering. You need to click the "Link to previous" icon from your Header/Footer tool bar. (again, hover your mouse over the icons to find it.) This step UNlinks you from the previous section with the roman numeral numbering
13. Follow steps 3-7 above (only be sure to change your number format to arabic and "start at" 1.
