[ka-Map-users] Newbie question : Where should I look for, errors when my keymap doens't work?

Jose, don't give up :-)

You just need to start with a simpler mapping framework than kamap 
(which happens to be one of the most sophisticated ones)

I started teaching a class this term on web mapping with open source, 
and we use Tyler Mitchell's book and Bill Kropla's. I would recommend 
you buy the Kropla (Beginning Mapserver) book and work through chapter 
FOUR. Once you've made it this far you will have all of the elements 
needed to implement a kamap version. You can download his sourcecode 
from the publisher's webpage.

I hope Tyler will make the code from his book available too ;-)

You need to make sure that you understand what *coordinate system* you 
are in, in order to make the reference map work!

Hang in there,
Percy
