Hi You didn't mention the error getting. I am seeing that you haven't your session variables set with some values. Please check below modified code. It's running. Session[ Correct ] = 90; Session[ Wrong ] = 10; int correct = Convert .ToInt32(Session[ Correct ].ToString()); int total = Convert .ToInt32(Session[ Wrong ].ToString()) + correct; double dbMark = 100 * correct / total; Response.Write(   + total.ToString() +   + dbMark.ToString());
