Drag and Drop with Multiple Targets

Hello, I am working on a drag and drop animation in Adobe Animate Actionscript 3.0. There will be 3 Do's targets and 4 Don'ts targets. There will be 3 draggable objects that can go in ANY of the Do's targets and 4 draggable objects that can go in ANY of the Don'ts targets. The drag function works but when I drop the object, it goes to the upper left corner of the screen, but I don't know what to change. If someone could please help me, I would greatly appreciate it. Here is my code: 

var draggableObjects:Array = [TapWaterDD_mc, ReplaceCaseDD_mc, NewSolutionDD_mc, DryCaseDD_mc, ShowerDD_mc, SwimDD_mc, SleepDD_mc];
var doTargets:Array = [targetDos1_mc, targetDos2_mc, targetDos3_mc];
var dontsTargets:Array = [targetDonts1_mc, targetDonts2_mc, targetDonts3_mc, targetDonts4_mc];
var objectsCount:int = draggableObjects.length;
var intargetsCount:int = 0;

// Enable dragging for draggable objects
for each (var draggableObj:MovieClip in draggableObjects) {
draggableObj.buttonMode = true;
draggableObj.addEventListener(MouseEvent.MOUSE_DOWN, pickupobject5);
draggableObj.addEventListener(MouseEvent.MOUSE_UP, dropobject5);
}

function pickupobject5(event:MouseEvent):void {
event.target.startDrag(true);
event.target.parent.addChild(event.target);
}

function dropobject5(event:MouseEvent):void {
event.target.stopDrag();

var matchingTarget:MovieClip;
var columnTargets:Array;

if (draggableObjects.indexOf(event.target) != -1) {
columnTargets = doTargets;
} else {
columnTargets = dontsTargets;
}

for each (var target:MovieClip in columnTargets) {
if (event.target.hitTestObject(target)) {
matchingTarget = target;
break;
}
}

if (matchingTarget != null) {
if (matchingTarget.numChildren == 0) {
event.target.removeEventListener(MouseEvent.MOUSE_DOWN, pickupobject5);
event.target.removeEventListener(MouseEvent.MOUSE_UP, dropobject5);
event.target.buttonMode = false;
matchingTarget.addChild(event.target as MovieClip);
event.target.x = matchingTarget.x;
event.target.y = matchingTarget.y;
intargetsCount++;
if (intargetsCount == objectsCount) {
advancetonextframe5();
}
} else {
// If the target already has a draggable object, return it to its original position
event.target.x = event.target.parent.x;
event.target.y = event.target.parent.y;
}
} else {
// If dropped outside any target, return the draggable object to its original position
event.target.x = event.target.parent.x;
event.target.y = event.target.parent.y;
}
}

function advancetonextframe5():void {
gotoAndStop(135);
}
