How do i dynamically update table of content page numbers as user inputs data and PDF gets larger?

I have a very large dynamic PDF and i have already built the table of contents but it only contains the title of each section (no page numbers). each item clicked focuses view on the corresponding Header of that section even if the page number changes. BUT now i need to add page numbers onto the table of contents page that will dynamically change as the document grows.  I'm new to LiveCycle.  Can anyone help? (I'm running LiveCycle ES4)
