Stuck at addingChilds... :S

Hello. I am trying to write a card game. I mostly completed it but when it comes to define the true or false, I get stuck! Here is my problem…

There are 3 choices for each card. User got 2 chances to find the correct answer. If user finds the correct answer a tick drops on to the card. if it is wrong a cross drops. It is okay till now. but when user gives a correct or false answer, all cards gets effected about the answer and a cross or a tick is added on to all of cards :smiley:

http://www.fenmatik.com/MaddeyiTa.fla here is the fla code. I tried to make it wrap in a class but could not succeeded.

what is wrong with my code? Why these ticks and crosses are added to the stage again and again?
