Guarav,

I contribute to this forum for a bit of light relief and getting to the bottom of your problem will take some work. Unfortunately for you I neither believe your statement that you wrote this nor do I think you have taken my advice to look at "use of the error object". If you had put in some effort and demonstrated that I might be inclined to help. The exhortation by you to "please explain me the exact mistake which I am doing and what should I do to make it work?" I just find irritating. I am unlikely to look at this thread again.

Good luck.
