So, I was able to get the button up and functioning. And although this is a small feat for many in this class, it was a very big deal to me. And I got it to work on Thursday, not Sunday at midnight, another wonderful thing. To get the initial button movement of backward and forward isn't what got me, it was the reseting of the images once they ran to the end. I finally realized I was making it too complicated (which is not unusual for me). Then I figured out that I was doing it correctly, except I kept using '==' instead of just '='. It's always the little things that get me. Big shout out to Candice because, honestly, once I heard her "just rotate it" button advice, I was unable to to get past it, and did just that.
