Urgency--Why are all the draganddrop quizs unfunctional

The big and green sound buttom has the sound of letter a, I want let the small a and big a and the buttom with the sound a can drag into the orange frame, but all of them are rebounded.
What’s the problem?

Could you please send us your project to support@atomisystems.com so that we can check?

OK, at once
Thanks a lot for your helps


Here are our instructions on how to make your slide work correctly:

  • Clear all the drop targets outside the slide.
  • Set correct answers by dragging the marker of each drag source into the drop target.
  • For the drop target: In the Properties pane > Styles & Effects tab > Line section > choose Solid Line, Width = 0.
