Drag and drop activity
in a drag-and-drop activity, I have the same proposal twice. To work around this problem, I put triggers on these proposals. But I encounter a new problem: if the learner deposits the other proposals in the right place, without depositing duplicate ones and validating the interaction, he validates the exercise. But he has not deposited everything. Do you have an idea ?
Attached is the storyline file. This is Exercise 1.4 Le pacte Dutreil.
Thank you in advance
