Hello to everybody. I am new in using flash 8 and i need your help

I have written this code
var s:String = “5”;
var s1:String = “5”;
var n:Number = parseInt(s);
var n1:Number = parseInt(s1);
var n2:Number = n+n1;
trace(n2);
but i need to read s and s1 from a text box value and display n2 on screen in a dynamic textbox .
Thanx
