I was able to get the scroll from the trainer and get to the Gym leader. So, I was able to fight the middle bottom trainer before getting the message that I needed the scrolls. Only until after leaving the gym to heal my Pokémon and re-entering the gym did I get the message. Somehow I bypassed the initial message and I'm guessing that's what caused this. My internet is a little spotty up at campus, maybe causing the bypass? I'm not sure, but regardless I appreciate it a lot. Thanks for the fix!
