Drag and drop with multiple scenes

I’ve taken the drag and drop tutorial from this site and adjusted it to suit my needs. Me and my co-worker have been trying all day to get this to work. Here’s a little of what my problems:

  1. Need it to do: when the correct word is placed in the box, it stays there. Currently it disappears. I think this is because we are removing the child, but if we don’t remove the child - it stays in all scenes and frames and interferes with being able to drop more words in the target box.

  2. If you incorrectly guess, then correctly guess… the incorrect guess is visible throughout the rest of the scenes and frames (this is a big one, i need this fixed somehow).

  3. Not as important, but in order to make this work, I had to go into each scene and make sure all my variables were named differently then the other scenes. There must be a way around this.

Any help is much appreciated!
