Hello butter cup,
How did you make the table of contents? if I'm understanding your question right I think you can have two or more types of numeral in one document and then make the table of content, which automatically will include your two type format of numbers.
to make a document with two different types of numbers :
1-click on insert>page number>format> number format>choose I,II,III>ok
2-go to the end of the page before the section where you want to have pages numbered as 1,2,3..
3-click on insert>break>tick next page under the section break types.
4- repeat step 1 but choose 1,2,3 and then under "page numbering" field tick start at and choose the number you want to start your new section with>ok
5-then select your heading for the table of contents and the office will automatically number your table of contents as your numbering styles.
these instructions are for word 2003.
Hope this will help
