Hi, I trying to set my document as follows.
=============================
1.   Introduction Chapter
1.1 Intro Section 1
       Figure 1.1
       Table 1.1
1.2 Intro Section 2
       Figure 1.2
1.2.1  Subsection
       Figure 1.3
       Figure 1.4

2.   Approach Chapter
2.1 Approach Section 1
       Figure 2.1
       Table 2.1
           E=mc^2    Eqn (2.1)
           F=ma        Eqn (2.2)
=============================

Something like that.  I can get the section numbering (1, 1.1, 1.1.1) but I
don't know how to set up the figure, table, equation numbering.
I want the first number to follow the chapter number, then the second
increase by one and then restart after a chapter change.

Thanks in advance.
