Using hitTestObject with 'if' statements in ActionScript - actionscript

Question

I am trying to use hitTestObject and enter_frame to create a "Test" page where the user drags an "answer box to another box, and if the answer is correct it displays the word "correct, if not "wrong", but I have four questions (q1) and 4 answers (a1), and after the first answer is entered, it doesn't do anything else, unless I move the square out of the correct answer.
How do I get it to work and ignore previous responses? I'm using the drag/drop commands as well.
-
finalTest.addEventListener(Event.ENTER_FRAME, detectCollision);
function detectCollision (evt: Event) : void {
if(a1.hitTestObject(q1)) {
finalTest.checkText.text = "Correct answer";
}
else if(a1.hitTestObject(q2)) {
finalTest.checkText.text = "wrong";
}
else if(a1.hitTestObject(q3)) {
finalTest.checkText.text = "wrong";
}
else if(a1.hitTestObject(q4)) {
finalTest.checkText.text = "wrong";
}
else if(a2.hitTestObject(q2)) {
finalTest.checkText.text = "Correct answer";
}
else if(a2.hitTestObject(q1)) {
finalTest.checkText.text = "wrong";
}
else if(a2.hitTestObject(q3)) {
finalTest.checkText.text = "wrong";
}
else if(a2.hitTestObject(q4)) {
finalTest.checkText.text = "wrong";
}
else if(a3.hitTestObject(q3)) {
finalTest.checkText.text = "Correct answer";
}
else if(a3.hitTestObject(q1)) {
finalTest.checkText.text = "wrong";
}
else if(a3.hitTestObject(q2)) {
finalTest.checkText.text = "wrong";
}
else if(a3.hitTestObject(q4)) {
finalTest.checkText.text = "wrong";
}
else if(a4.hitTestObject(q4)) {
finalTest.checkText.text = "Correct answer";
}
else if(a4.hitTestObject(q1)) {
finalTest.checkText.text = "wrong";
}
else if(a4.hitTestObject(q2)) {
finalTest.checkText.text = "wrong";
}
else if(a4.hitTestObject(q3)) {
finalTest.checkText.text = "wrong";
}
else {
finalTest.checkText.text = " ";
}
}

Maybe this should help:
var questionArray:Array = new Array(q1,q2,q3,q4);
var answerArray:Array = new Array(a1,a2,a3,a4);
var checkId:int = 0;
for(var i:int = 0; i<answerArray.length; i++) {
answerArray[i].ids = i;
answerArray[i].addEventListener(MouseEvent.MOUSE_DOWN, onDragHandler);
answerArray[i].addEventListener(MouseEvent.MOUSE_UP, onReleaseHandler);
}
function onDragHandler(e:MouseEvent) {
e.currentTarget.startDrag();
checkId = e.currentTarget.ids;
}
function onReleaseHandler(e:MouseEvent) {
e.currentTarget.stopDrag();
if(e.currentTarget.hitTestObject(questionArray[checkId])) {
finalTest.checkText.text = "Correct Answer";
} else {
finalTest.checkText.text = "Wrong";
}
}
I make the question and answer into array. And i didn't use ENTER_FRAME..
