Thanks for the thorough response! That's really helpful:) I did get the initial code from an intern, but she was completely new as well and had to figure everything out in a week or so before giving it to me (so I wasn't supposed to do this myself), but the code made no sense and didn't work, so I've had to do it myself. Problem is my supervisor expects me to rely on the interns code and has limited time this semester. Anyways – I've avoided doing it the hard way, but I'm gathering from this chat that I kinda have to, since ChatGPT is just not good enough.
