Hi Araz,

That means Java doesn't now what timerText is so it has not been declared. Can you paste your code into here and we'll get that sorted for you.

I just changed

from:

        public void setmTimerText(String TimerText) {
            mTimerText.set(TimerText);
        }

to:

        public void setmTimerText(String mTimerText) {
            this.mTimerText.set(mTimerText);
        }

Then the cannot resolve symbol timerText disappeared but still i cant see the hammer text when running the program!

You have to remove the 'm' from your setter and getter in the variable name. you have this: public void setmTimerText(String mTimerText) { this.mTimerText.set(mTimerText); } you need this: public void setTimerText(String mTimerText) { this.mTimerText.set(mTimerText); }
