I fear I can't help you much, but I would raise several points:
- You should indicate the platform on which you are running Lua... Are you 
sure you have the rights to write a file where you want? AFAIK, your code 
will (try to) write the etc file where your script is. You may want to 
specify a path.
- Unless you have a very specific need for it (mandatory at your place?), 
you should probably drop Lua 3.2 to use Lua 4.01. Lua 5.0 is on its way, 
but still alpha as the time of writting. Lua 3.2 isn't bad, of course, but 
a bit outdated and slightly more primitive :-)
