Thanks a lot for your quick response. I actually just found the answer by myself before reading your reply. Just printed out the code and read it. The mistake was pretty obvious then. Yes, Ill try your suggestion. I was just trying to experiment a bit with inheritance to understand how it works better.
Once again thanx a lot. Its the first time I post and Im pretty impressed by the speed with which you guys replied.
