AS3 script to detect spacebar press and score using incremented var

Question

Hi,
Continuing work on eLearning project exercise see: http://forums.adobe.com/message/4682999#4682999
Based on kglad's script there, I am trying to add scoring by detecting a spacebar press when a specific text item is displayed. If the user presses the spacebar while the text is in the text box, then it would increment a variable by +1 (++).
The script I've written to test this (using 1 var for one type of correct "hit" and a second var for a second type of "hit"), when added to the other script, doesn't work. The Flash debugging player freezes. A trace does not show anything, including incrementing of the variable.
Here's the script:
stage.addEventListener(KeyboardEvent.KEY_DOWN,checker);
var targetHit:int;
function checker(e:KeyboardEvent){
while (wordT.text = "3")
   if(e.keyCode==Keyboard.SPACE){
       targetHit++;
       trace(targetHit);
stage.addEventListener(KeyboardEvent.KEY_DOWN,checker2);
var distractorHit:int;
function checker2(e:KeyboardEvent){
   while (wordT.text = "5")
   if(e.keyCode==Keyboard.SPACE){
       distractorHit++;
       trace(distractorHit);
Any suggestions on fixing this script would be appreciated.

Thank you for this helpful suggestion.
By way of explanation:
If the user sees a specific correct "target" word displayed during the 1000ms that it is displayed in the text box, and they press the spacebar, they would receive a +1 added to a score var (targetHit).
The exercise also needs to score/keep track of incorrect hits: when the user presses the spacebar when a specific distractor word is displayed during the 1000ms that it is displayed in the text box. This spacebar press would add +1 to the var distractorHit.
Substituting "if" seems to work.
Now, with the practice blocks of 16 each working sufficient (can tweak them later), need to move on to a slightly more challenging part of the exercise: the 70-word trial blocks.
Will close out this posting as "correct" and post a new question related to the more challenging 70-word versions.
