I can't get this code to compile. What am I not seeing? 
 public void act() 
    {
        // Add your action code here.
    }  
    public void moveArrowKeys()
    {// start method
        // See if any keys are down
        if (Greenfoot.isKeyDown("up"))
        {
            // Move UP one position
            setRotation(270);
            setImage("cat-walk-right.png");
            move(5);
            Greenfoot.delay(5);
            setImage("cat-walk-right-2.png");
            move(5);
            Greenfoot.delay(5);
        }
        else if (Greenfoot.isKeyDown("down"))
        {
            // Move DOWN one position
            setRotation(90);
            setImage("cat-walk-right.png");
            move(5);
            Greenfoot.delay(5);
            setImage("cat-walk-right-2.png");
            move(5);
            Greenfoot.delay(5);
        }
        else if (Greenfoot.isKeyDown("right"))
        {
            // Move RIGHT one position
            setRotation(0);
            setImage("cat-walk-right.png");
            move(5);
            Greenfoot.delay(5);
            setImage("cat-walk-right-2.png");
            move(5);
            Greenfoot.delay(5);
        }
        else if (Greenfoot.isKeyDown("left"))
        {
            // Move LEFT one position
            setRotation(0);
            setImage("cat-walk-right.png");
            move(-5);
            Greenfoot.delay(5);
            setImage("cat-walk-right-2.png");
            move(-5);
            Greenfoot.delay(5);
        }
    }// end method 
}

It would be much easier if you would show the error message and tell us where it occurs.

That's the problem no error message is given, it just won't compile.

What do you mean by "compile"? If there's no error message, the compile was successful. It might not do what you want, however. In this case, your act() method does nothing. You have a moveArrowKeys() method, but it is never called. Perhaps you meant to call the moveArrowKeys() method from your act() method?

davmac the code was input straight from what my teacher gave us. Once I enter the code listed, I hit compile and it just clocks meaning something is not right in the code, but I can't see what.

What do you mean by "it just clocks"? Can you be more specific (or descriptive) as to what is happening?

Nothing happens what I press compile. Compiling just shows at the bottom. After about five minutes I have to do a Ctrl - Alt -Delete to end the task and reopen it up to see what code is causing it not to compile. I wish i could send you a screen shot.
