Thank you so much. I really appreciate your help. Actually confusion was about my email address. I have two different email addresses for the ID newstudent. When I made my new id newstudent1, I have used an email address that I had also used for ID newstudent. So this has just confused me as I have given same address to both ID's.

Lolz my explanation is more confusing ....

Chalain ab solve ho gayi problem. Thanks again.
