So, I found a program for a TI84 Plus and used this website to convert it from .8xp to raw TIBASIC format, and the code works perfectly in this website's emulator, but I get an overflow error when I try using it on my physical calculator. Here is the code:

Keep in mind that this program is NOT mine, I was just converting it into TIBASIC because I don't have a data cable that can plug into my TI-84 and transfer programs.
