I have the following problem in drag and drop interaction:
When the learner makes a mistake, click Try Again and continue to do the same as slide 1.
But slide 2, when the learner makes a mistake, he/she press Try Again, the learner can't work anymore.
I want the learner to continue working on the old results like slide 1 and not want to start over when clicking Try Again
i don't know where my problem is ? Anyone help me ?
