Answer 1

It’s a pitfall of TP5. I also reported an error after watching the video like this. I don’t think empty can be used to judge the defined constant (that is, the constant AA you defined). I used a variable to catch it before judging. Define constants and then use them for judgment. It actually works (ー_ー)!! What?
