I am a new LateX user. I more or less start to understand how LateX works.

However, I have a problem with the references.
I am using Jabref 2.4.. Somehow, the references are not recognized
when I create the pdf file.
On the command window, this appears:
Citation 'YY' on page XX undefined on input line XX
As a result, the pdf file is created with [?] .
My .bib file opened in WinEdt starts with:
% This file was created with JabRef 2.4.
% Encoding: Cp1252
