Clearing the stage

Question

Hi,
using the code below, i've created a basic drag and drop question and answer, where the user can drag the correct answer into the question box. However when moving to the next slide any objects moved on slide 2 remain on slide 2. I've tried removechild but this did not work (i'm probably doing it wrong). I'll add i'm a complete novice, i've only been using falsh for a week now.
Many thanks in advance

Answer 1

Sorry for the poor terminology. I have 1 slide/scene with a question and the answers, then I have one button that resets and one that moves on to the next question, but when I move to the next question (I inserted another frame) any items moved in previous question appear with the next. Sorry if I'm not explaining myself very well but I've only been using flash since last Saturday.
Thanks
