Thank you to everyone for the help it was a stupid mistake that I still can not understand. I changed GWT sdk and the program worked, then I used the old SDK to ensure that the problem emanates from the sdk but the surprise the program still works ':(.
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.
