Piclist.com as well as a quick google search will turn up several examples
of a pic to 4 bit character LCD interface.  A more specific description of
the problems you are having would be helpful.  Simply saying "it doesn't
work --please fix it" without source snipit or details isn't going to get
you anywhere you want to go.

Several things can go wrong when communicating with an LCD module.  Is the
contrast set correctly?  Are you getting any response to programming
commands (does the lcd initialize/clear the screen)?  Sometimes it helps to
put a lot of delays into the code and probe each step to see if the
processor is outputing bitpatterns as expected.  It's difficult to guess
without knowing what is or isn't working.
