this.createTextField("myTxt", 20, 0, 0, 100, 20);
myTxt.type = "input";
myTxt.border = true;
myTxt.restrict = "0-9";
this.createEmptyMovieClip("submit_mc", 30);
submit_mc.beginFill(0xFF0000);
submit_mc.moveTo(0, 0);
submit_mc.lineTo(100, 0);
submit_mc.lineTo(100, 20);
submit_mc.lineTo(0, 20);
submit_mc.lineTo(0, 0);
submit_mc.endFill();
submit_mc._x = 110;
submit_mc.onRelease = function(evt_obj:Object):Void {
var myNum:Number = Number(myTxt.text);
if (isNaN(myNum)) {
trace("Please enter a number");
return;
}
if (myNum >= 10) {
trace("Your number is greater than or equal to 10");
} else {

trace("Your number is 10");
} else {
trace("Your number is not 10");
