table of contents page numbers are all question marks

[Chip]

In using the sample code from NR 3.2.4 Table Of Contents I get all my 
page numbers as question marks. Even the example shows all the page 
numbers are page 1. There is no info on how to get the page numbers to 
increment, or how to manually insert the page numbers. (I did search the 
archives and used google but found no answer.) My code is provided below.
