How you can see here your code work with the data. I suspect that the data returned from the server either not have exactly the same data which you posted or the server response has the wrong content type. I recommend you examine the server response with Fiddler of Firebug .
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
