Animation only plays once

I'm probably missing something very simple. I have a simple file where I have a 2 layers. On one layer, I have a "show me" button that has a trigger to show the 2nd layer. When the second layer shows, a rectangle flys into the slide from the left. The second layer also has a "close" button that simply hides layer 2. This works, I click the "show me" button and layer 2 appears and the rectangle animates onto the slide. If I click the "close" button and then click the "show me" button a second time, the rectangle doesn't animate back onto the slide, the rectangle is already displayed. Is there a way to reset the animation with a trigger?

Thanks in advance for any suggestions.
