    Why wont this number validator work?  (Small program - need help)

    brds Level 1

      I need to use the number validator for a school project.  I have to have the user select their birthday from a calendar.  After selection of their birthday, the user will click the validate button.  Once the button is clicked, the validator should verify if the age is above 15.


      For some reason, the number validator isn't working on the click of the button.  Here's the code i've come up with... any help would be appreciated:


      <?xml version="1.0" encoding="utf-8"?>
      <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" verticalAlign="top" horizontalAlign="center" backgroundGradientColors="[0x000000,0x323232]" paddingTop="0" viewSourceURL="srcview/index.html">
                  import mx.controls.Text;
                  import mx.controls.Alert;
                  [Bindable] public var minAge:Number = 15;
                  [Bindable] public var age:int;
                  public function displayDate(date:Date):void
                      if (date == null)
                          selection.text = "Date selected: ";
                          selection.text = "Date selected: " + (date.getMonth()+1).toString() +
                          '/' + date.getDate() + '/' + date.getFullYear().toString();
                      var now:Date = new Date();
                      age = int(now.fullYear) - int(date.getFullYear());
                      if ((date.getMonth()) >= now.month)
                          if ((date.getMonth() == now.month) && (date.getDate() > now.date))
                  public function showAlert(result:Boolean):void
                      if (result)
                          Alert.show('You have successfully validated your birthday');
                          Alert.show('Sorry, you are not old enough');
          <mx:NumberValidator source="{age}" property="text" minValue="{minAge}" domain="int" trigger="{vButton}" triggerEvent="click" valid="showAlert(true);" invalid="showAlert(false);" />
          <mx:Panel title="Select Your Birthday" width="600" color="0xffffff" paddingTop="10" borderAlpha="0.15" height="240" layout="horizontal" horizontalGap="15" paddingLeft="10" paddingRight="10" paddingBottom="0" horizontalScrollPolicy="off" verticalScrollPolicy="off">
                  <mx:DateChooser id="birthday" yearNavigationEnabled="true"  height="145"  
                    change="displayDate(DateChooser(event.target).selectedDate)" color="0x000000"/>
                  <mx:Label id="selection" color="0x323232" text="Date selected:"/>
              <mx:Canvas width="369" height="179">
                  <mx:Button id="vButton" label="Check Birthday" labelPlacement="left" color="#000000" />
                  <mx:Label id="showage" y="160" text="{age}" color="#000000"/>
