Tell us what’s happening:
what is it im doing wrong?? also just a general question as the reader(you) are aware chatgpt helps majorly with coding, if i use chatgpt is it considered cheating, i was thinking this because in jobs and in the real world you use chatgpt so why not use it now??
Your code so far
