3 Drawers Open/Close Sequentially

Hello everyone.beginner here.I have created this blueprint that opens these 3 drawers sequentially. That is, it opens and closes drawer 1, opens and closes drawer 2, opens and closes drawer 3 smoothly according to the timeline. When the first round is finished, in the second round, the drawers open and close without the smoothness of the timeline.How can I make the series continue with the smoothness of the timeline?
