Vertical spacing before and after subsection headings and in TOC

[Bradley Navarro]

Hi all,

I have two final problems I am hoping someone can help me with. First, I 
need to know how to define the vertical spacing before and after a 
subsection heading. For example,

[defined spacing]
1.2.2  Instrumentation
[defined spacing]
[text begins]
The code on Herbert's tip page for this does not want to work. Here is 
the code for reference:

\makeatletter
\newlength{\mySpaceUnder}
\newlength{\mySpaceOver}
\setlength{\mySpaceUnder}{4cm plus .2ex}  % 4cm as an example ;-)
\setlength{\mySpaceOver}{3cm plus -1ex minus-.2ex}   % 3cm as an example

                                  {\mySpaceOver}%
                                  {\mySpaceUnder}%
                                  {\normalfont\Large\bfseries}}
\makeatother
I changed 'section' to subsection in the above code. But when I try to 
view the dvi output, it says the resulting document is empty. If I try 
to view it a second time, I receive no error message but the changes do 
not take effect.  Can someone help me with this?

The second problem I am having is in the TOC.  I need the vertical space 
after the chapter title to be double instead of single spaced. For example,

1  Introduction........................... 1
[change space here to be double instead of single]
   1.1 blah.................................. 2
   1.2 blah.................................. 3
I am using lyx 1.3.3 in the report class.
Any help for these two problems would be greatly appreciated. Thanks.
