As far as the terminal window, your error message started with java.lang.NullPointerException at Score.<init>(Score.java:20) which is telling by '(Score.java:20)', at line 20 in the Score class, there is not something (or rather nothing ) where you are trying to get something. In your case, line 20 was the line that deals with the Font, and is trying to getFont() on 'image'. But 'image' is not yet initialized (it is still null), until line 30 of your most recent code post.

i see, so the null pointer exception is saying im trying to reference something i haven't yet declared, below it is the class where the error is, and in "class.java.int" int would be the line in the class?

You may want to slow it down as it will be increasing as fast as how many frames per second the scenario runs. If you wish to slow it down some, add a couple extra instance integer variables to the class 
private int maxCountdown = 40; // adjust value as needed
private int countdown = maxCountdown;
and change your act() method to 
public void act()
{
    countdown--;
    if (countdown == 0)
    {
        add(1);
        countdown = maxCountdown;    }
}

No problem. Glad to be of some help. I do not usually mention this, but you might want to check out some of my scenarios. There are a couple that have re-usable classes in them (a Bar class with multiple uses, including a health bar, or progress bar; and a Menu/Sub-Menu class combo; also, there is a true-time timer).
