Making a button that goes back steps in a sequence

[EC_9946980]

I am wondering how to make a button that can go back a step in a sequence. I have a button that if I click it, one step of the sequence will play. I also have a button that will replay the step. I would like a button to go back steps and am unsure of how to do this.
