I have word 2007.

How do I make my TOC into two columns? I've tried making the TOC and then
clicking on it and going to the Page Layout and selecting 2 Columns but when
it puts it like that the page no.s don't show up. The book I have tells me to
go into References and clicking on TOC and then click modify, but I am not
able to click onto the modify button.  

I have a book and I'm trying to get the page no's correct. My TOC page no's
are in i,ii,iii and I was able to put Chapter 1 into chapter-pageno.. The
problem is that for chapter one it comes up as 2-1. How can I change it so it
goes to 1-1.

For a chapter title, sometimes I can double click on it and get the menu "
Set Numbering Value" and other times I do not get this menu. For the times I
don't get this menu, how do I go about getting it?

Thank you!!!!!
