InDesign 5 can't generate TOC. Can you help me,please?

Written by Erika ErikaAUG on September 10, 2011

I’m learning InDesign 5 from scratch all goes well, but when tried to make a Book got  serious problems with creating TOC by following the instructions in Help. 
The situation is - when  I set TOC by the manual and click  on the page, just a blank text box appears displaying only the title I gave to  TOC ( “THE  Book contents”) but nothing else!
I could make  TOC by hand but want to learn how to make InDesign to do this. The book consist  of 3 chapters, TOC page and Index page properly saved as .indd documents entered in a “My new book” document I’ve created.
