I’m having an issue printing values from a list that feeds into a function print_list. For whatever reason, it only prints one element from a list, the greatest one, which is a separate issue in a different file.

I’m not sure if I’m pointing to incorrect addresses, or if I’m not retrieving them correctly. I have a hunch that says there’s something wrong with the loop itself, but I’m not sure
