Can I have multiple correct drag object/drop target combinations?

Two things:

I couldn't get it to drop right because the items only drop on correct drop spots. Maybe you want it that way, but if you don't you need to make the incorrect targets potential targets. If you create a regular drag and drop, you can identify which objects are potential drop targets. The only way you can do that using another kind of slide is to identify potential drop targets in a trigger. So I copied the triggers and changed them "Change state to Drop Incorrect" if person is dropped on wrong target. That way the person can be dropped on any target.

The other thing is that you were dropping them on groups. I used a group in SL once, and it worked the way I wanted. I think it was in 19...  No, wait. I'm thinking of another program, Maybe ...  Well, it doesn't matter; the point is that groups don't work in SL. Pretty much you can use groups, or you can have triggers and states that work, but not both. In the attached sample, I changed two of the groups to rectangles with words on them, and two of them to text boxes with a color fill. I would suggest that you can't tell by looking at them which is which, and you can't tell by looking which slide has the groups, and which has the rectangles and text boxes. You can tell them apart when you preview them; the one without the groups is the one that works.
