Displaying Score in the textfield

I am developing an android drag and drop game..I have a dynamic textfield name score1. when I use the command trace the score calculates correctly according to its calculation formula..but when i want to display it to the textfield it don't appear..can anyone help me?

Code:

stop();
import flash.text.TextFormat;
import flash.text.TextField;

//Score
var score:Number=0;



btn_nextCO1.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndPlayFromFrame);

It's hard to tell what the issue is without seeing the textfield in the .fla. Are you getting any error messages? If you have the wrong path you'll get an error. Is the font the same color as the background? Covered? Is there an issue with a loaded font?

Programming wise, you need to clean up your code too. A simple rule that might help is that when you look at your code (simply look at the words), you shouldn't see anything repeating. For example, in your first function you see this reapeating "item1_mc.visible=false;" with only the number changing. So replace the only part that changes with a variable and use a "for" loop:

Code:

---

for(var i:int = 0; i < 10; i++){
                this["item" + i + "_mc"].visible = false;
        }

---

See how the above code doesn't repeat? I know I could find better words for what I'm trying to say.
