Reply animation

I'm new to Storyline and I'm trying to create an animated slide with a replay button, but I can't figure it out, can this be done? If yes, how do you do it? If no, does anybody have a work around? Right now I have two identical slides with a replay button that loops from one slide to the other (object trigger). The problem with this is when I click the replay button a third time the animation doesn't replay again. The other thing I don't like about this set up is the fact that I have two sides. I really want just one slide and have the ability to replay the animation after clicking the replay button, creating unlimited replay. I have attached the Storyline file if anybody wants to play around with it.
