I am new to the scheduler and have a question. I have a series of timelines in two groups. The first group will play starting at 8AM and end at 4:30PM. The second group will start at 4:30PM and end at 10:00PM The first group has two timelines each 30 seconds in duration. The second series has 6 timelines lasting 75 seconds. I think I understand how to place them in the scheduler but I'm not sure they will repeat for the length of time I want them to play. What am I missing?
