Actionscript Functions Help

Question

Hey, can someone please help me find a solution in this code that i've got. I'm using this code to make gameplay mechanics of a rhythm game but there seems to be a problem with the code that i've coloured in red.
var timer1:Timer = new Timer (1000,1);
timer1.addEventListener(TimerEvent.TIMER, addRed);
var score:int;
stage.addEventListener(KeyboardEvent.KEY_DOWN, hitRed);
function addRed(e:TimerEvent){
          var activeRed:red = new red();
          activeRed.x = 75;
          activeRed.y = -100;
          activeRed.vy = 7.5;
          addChild(activeRed);
          activeRed.addEventListener(Event.ENTER_FRAME, animRed);
function hitRed(activeRed:KeyboardEvent){
          if (activeRed.keyCode == Keyboard.S){
                    activeRed.target.removeEventListener(Event.ENTER_FRAME, animRed);
                    activeRed.target.parent.removeChild(activeRed);
                    score += 1
function animRed(e:Event){
          var borderBottom = 800 + (e.target.height / 2);
          e.target.y += e.target.vy;
          if(e.target.y > borderBottom){
                    e.target.removeEventListener(Event.ENTER_FRAME, animRed);
          e.target.parent.removeChild(e.target);

If you are getting that error, things are not likely to work in any case. 
The 1009 error indicates that one of the objects being targeted by your code is out of scope.  This could mean that the object....
- is declared but not instantiated
- doesn't have an instance name (or the instance name is mispelled)
- does not exist in the frame where that code is trying to talk to it
- is animated into place but is not assigned instance names in every keyframe for it
- is one of two or more consecutive keyframes of the same objects with no name assigned in the preceding frame(s).
If you go into your Publish Settings Flash section and select the option to Permit debugging, your error message should have a line number following the frame number which will help you isolate which object is involved.
