"Exit" in director is ? in Flash

Question

Another in my series of "switching from Director to Flash" questions.
Here's what I'm trying to do.
1. Allow the user to type a new in an Input Text box.
2. If the number is from 1 to 12, go to the "input" frame
3. If the number is not from 1 to 12, tell them to type a number from 1 to 12 and give them another chance.
Here's the problem. If the user types a anything that is not a number from 1 to 12, when they try again and type a number from 1 to 12, the Input Text box is cleared, and program does not advance to the "input" frame. I'm guessing that I need to exit the If/Else. In Director, I'd type "exit". What do I do for Flash?
txt_defNumber.addEventListener(KeyboardEvent.KEY_DOWN, reportKeyDown)
var Term = ""
var Definition = ""
function reportKeyDown(event:KeyboardEvent):void {   
if (event.keyCode == Keyboard.ENTER)  {         
    var gNumber = txt_defNumber.text;
    if (gNumber == "1") {
        Term = "value"
        Definition = "A number and unit that together represent the result of a measurement or calculation, e.g. 100 meters."
        gotoAndPlay("input");
    } else if (gNumber == "2")  {
        Term = "unit"
        Definition = "A defined quantity based on a standard, e.g. meter."
        gotoAndPlay("input");
    } else {
        txt_incorrect_number.text = "Please type a number from 1 to 12."
          //What goes here?

Answer 1

use:
txt_defNumber.addEventListener(KeyboardEvent.KEY_DOWN, reportKeyDown)
var Term = ""
var Definition = ""
function reportKeyDown(event:KeyboardEvent):void {
    if (event.keyCode==Keyboard.ENTER) {
        var gNumber=Number(txt_defNumber.text);
        if(gNumber>=1 && gNumber<=12){
            gotoAndPlay("input");
        } else {
            txt_incorrect_number.text="Please type a number from 1 to 12.";
        }//What goes here?
