Is it showing a compiler error? post the errors
Is it showing unwanted output? post the output
Do you know how to properly format your code and wrap it it in code tags before you post? If yes then do so

thank you very much for your reminding, I really have not wrap all of code before post. It disappear about 1 or 2 lines. Now I can solve it .
