    Hello Mob31,

    Please don't write URGENT!!!! in your thread titles. Everyones issue is urgent as far as they are concerned.
    People will help answer your question as soon as possible regardless of you writing this.

    The problem here is with your if statement.

    Take a look at this line:

    else if (Choice ==2);

    You need to remove the semicolon ;

    This will work fine now!

    Also, please make sure you initialize your variables.
    Please use [highlight=Java] code [/highlight] tags when posting your code.
