Drag and drop not working

The built-in Try Again button merely hides the feedback layer so the learner can make a second attempt. If you jump to the base layer and reset it, you will also reset the number of attempts. One way to make that work is to use a variable to keep track of the number of attempts, and jump to the incorrect layer when the Try Again layer opens if the maximum number of attempts has been reached.

Not only is that a lot of extra work, but showing the learner the errors, and letting them correct them (by dragging incorrect answers to correct spots) improves learning. You may or may not want to indicate which answers are incorrect.

However, if you are insistent on resetting the slide, I attached a sample project that does that near the end of this thread:
