Hi, I have made significant progress in my task, thanks for the help, I really appreciate it.
I might not have the most efficient coding, but things are working as expected now. One might come up with the answer I asked, but I think he has to read all the article carefully in JIA and online help, just hope that this will be documented somewhere in future. I have read those reference a lot of times, maybe I have not got Expert System concept well enough. Again, tq :) Calvin __________________________________ Do you Yahoo!? New and Improved Yahoo!
