hi danpost First to begin, let me wish you happy new year and secondly let me tell that you I pass the first and second assignment that you guys have help me with. I got tow A's but an overall i got a D which was quite disappointed though but I pass the course so now I am going on to object 2 programming. and with that i have started practicing building some program. three of them, one is the simulation of the operation of a pizza restaurant, another banking system and a calculator. I have reach as far a building the gui panel for each of them but it is just the coding to get it to work but right now I am more concentrating on the calculator. the calculator is a thre tabs meaning it is a standard, scientific and binary I have code the standard and the scientific par tof the calculator but the binary part(at least not as yet) but somehow is is not working . can u tell me what is work but how do i upload it foor you to see

First open a new Greenfoot scenario project, call it 'Calculator help'. Create a subclass of World so greenfoot is happy that you have a World subclass. You could copy the following code into that class (replacing everything that is already there): 
import greenfoot.*;

public class MyWorld extends World
{
    public MyWorld()
    {
        super(600, 400, 1);
        GreenfootImage text = new GreenfootImage("Calculator\n\nHelp", 80, null, null);
        getBackground().drawImage(text, 300-text.getWidth()/2, 100);
    }
}
Now, for each and every class in your calculator project create a new class and copy/paste their codes (use the menubar and select 'Edit>New Class...' to create a new class). Now, select the body of the class(es) (all but the MyWorld class) and comment the code out so any errors are eliminated. Then click the Compile button at the lower right of the greenfoot frame. If you followed my instructions okay so far, it should compile. Finally, click the 'Share...' button at the top right of the greenfoot frame and select the 'Publish' tab along the top. Check the 'Publish source code' checkbox, enter your greenfoot username and password along the bottom and click the 'Share' button. It will upload to this site where it will be accessible to myself and others.

Maybe you never downloaded the greenfoot application to your system (see 'Download' link near top of page).

You tabs have nothing to do with the errors you are getting. You need to show your ATM class code. You are getting 'cannot find symbol -- variable client' compile errors in that class.

HI Dan post This is not the atm program, this is the calculator that am currently working on actually

These images are not going to help much by themselves. Will need to see codes. Post them here if you have to (at least the pertinent classes).
