How to make func_pathtrain loop

[CyanideNoodles]

I'm trying to make it like darts are going back and forth in a loop. Ive had it in other maps before but I wasn't the one who made it do that and I no longer have access to help from that person. It goes to the path_1_b I want it to contentiously go from path_1_a to path_1_b and have a trigger_hurt attached to it. What else do I need to do to make it loop? I can't find anything .

Set the "Next Stop Target" in path_1_b to path_1_a.
