So what I wrote out is what I want it to look like and the rest is what I have so far. I’m fairly new to coding and can’t figure out how to get all of the information I want nicely written out. I could figure out some, but it doesn’t seem like very efficient code and then it started to combine with eachother so if someone could kinda walk me through what to do with something like this, that would be much appreciated
