Sorry,I didn't try to change the statement of button during animation,I try to change the statement before animation. When animation start, I wish the button is already invisible,thanks – user515909 Nov 23 '10 at 4:07 Can you post code relating to where 'button' is created? – Mark Adams Nov 23 '10 at 19:44.

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.
