Abdelhalim,

For someone to be able to answer your question you should prune your 
stylesheet down as much as possible to isolate the problem.  Then you 
should post the XSL code to the newsgroup so that people can examine the 
problem.  You should be able to get the XSL code down to under 20 lines; 
  anything more and people will be less inclined to offer comments.

Cheers
Justin Johansson
