Drag and Drop objects to the same target

Can any one assist? I have a box that has six labels that can be dropped on targets on the box. I have all this in place but I want to be able to have label 2 drop onto target 2 and 3, and likewise label 3 drop on to target 2 and 3. All others drop onto their specific targets. This is the script so far but ony for matching object to target. Please be gentle, i'm new to this!!

event.target.stopDrag();

var myTargetName:String="target" + event.target.name;

var myTarget:DisplayObject=getChildByName(myTargetName);

if (event.target.dropTarget!=null&&event.target.dropTarget.parent==myTarget)

Can anyone assist please?
