Hi...I am a teacher. I am new at this program. I just want to make a drag-drop activity for my students on html5 and did it after watching this video*. But I also want to hear a "true" sound after dragging the answer but I couldn't make it. I am adding to "no sample is playing" in 7th line and setting it as play sample sound. It is ok but it is looping. I don't want this looping. Can you help me, please?
