Hi
Can some help me to indent my document.
In my document, I have heading and sub heading that are hyperlink
Ex
13. xxx
13.1 xx
13.2 xx



14. yy
14.1 yy
14.1.1 yy

Now if I need to insert another heading in between 13 and 14, how can I do
this, so that the heading & subheading underneath also get updated
according.
In this example, If I insert a heading # 14 between 13 & 14, the heading #
of 14 should chnage to 15 and all the subheading should be changed to 15.1
etc.

Please advise
