Question Cycle animations on button click

I have a 3D building floorplan that I want to be able to click the up and down arrows to cycle through floors. I have animations set up for each floor. I have the first button playing the roof leave animation but I would like it to step down and up based on the arrow presses.





Can I accomplish this with simple On Click commands for the button or will I need to write a script to get it to function correctly? I am currently trying to teach myself programming but I don't know much. Any help would be greatly appreciated.
