File Name: interval_logic_and_events_1.htm Expected Behavior: the smile image is shown from 0 to 20s the video2 begins at 5s and plays until 15s. the video1 is shown at 10s, starting 5s into the video. A click before 10s will do nothing. After 10s, video1 will play until a click occurs on the smil image. If no click occurs between 10s and 20s, then there is no way to generate the smile.click and the video will play indefinitely.
