Your question is not very clear (to me). Can you show the code you are using to load the movieclip into the container, and explain what you are trying to extract from where in that combination of objects?
As I want to build a supermarket interface with number of 2x3 or 2x2 cells in every shelf,
I prepare at least more than 6 items in 1 mc for attachmovie randomly in each cell.
On the other hand, I need to attachmovie of the selected items in a shopping cart list with quantity information, and
removed it in cart list when click until tthe quantity is zero.
So, I added a button inside the attachmovie to count and store the times on each frame click and currentframe no with items id in array.
Now is much trouble to store array item_id[n] without repeat, if repeat, add to item_qty[n]++
