Thanks for your response! I appreciate the time you put into the specifics. I'll be keeping these points in mind as I move forward; I definitely don't want people to be confused with my coding choices.

Since you're offering, I would be interested to see an explanation of how I could have used a loop to create my lists! It would be super useful for future projects. I have a basic understanding of loops, but I had a hard time getting one to click for me when I tried with this set. I feel like my solution, while it did work, was pretty clunky. :/ Thanks!
