1 Chapter 1
1.1 Section 1.1 . . . . . . . . . . . . . . . . . 8
1.2 Section 1.2 . . . . . . . . . . . . . . . . . 11
2 Chapter 2
2.1 Section 2.1 . . . . . . . . . . . . . . . . . 31
2.2 Section 2.2 . . . . . . . . . . . . . . . . . 34
which are unclickable and I need to make them clickable. For example when I click on Section 2.1, I need to jump to page 31, and so on … what do I need to do given I have adobe reader pro?
