I have a mystery to solve.

My drag and drop puzzle, with 3 correct positions, was working until I changed
the graphics (from bags to boxes).

Now only two of the positions will trigger correct results when my check
button script runs. When in correct position movieclips play frame 2 with check
mark; when incorrect play frame 3 with X-mark.

All the 'labels' when placed on positions 1 and 3 work. But none of them work
on position 2.

It would also be great if I could find a way to reduce all this code. (I know
there should be a function, or ways to cut down on repetitions; I get confused
about a. how to write it and b. where to put it.)

If you are interested in helping, please be very basic in your response. I
plod.

[Code is below. SWFs attached. Can try to reduce FLA size and upload if
someone wants to see that.]
