order of drag and drop elements

I'm building a drag-and-drop question and having issues with the correct answer being "tallied". There are 7 elements that drag to two areas of a jpeg graphic. I've built a button for the page that works as a submit button with conditions set to the answer being TRUE or FALSE.If I drag the elements to the correct area of the graphic in the order they were built, it works fine. If I drag the elements to the correct areas of the graphic in random order, the answer comes up as incorrect.I can request that the user work in numerical order but would like to let them randomly place items and have it work just the same.Any help on this would be appreciated.
