Mindstorm light sensors

[BCZM]

i would like to know is there any way to get the input from the mindstorm light sensor and display it on the LCD??

i am using nxt 2.0

example... i will write the number "1" on a piece of paper and would like this 1 be display on the LCD of the processor when the robot's light sensor scan this "1"

below is my code:

task main() {
 SetSensorLight(IN_1);
 int light=0;
       light=Sensor(IN_1) ;
     ClearScreen();
     ResetScreen();
            NumOut(0,0,light);

 Wait(20000);

Off(OUT_AC); // stop and end program gracefully
StopAllTasks();
}

 the result of the above code is that no matter what i write on the paper... the LCD will keep displaying 100
