I see, thank you. About that error though, if the problem is that self.book_code = "" is nil, then I’m either thinking that my goal is to make it either a local variable or to reorder when I create that variable. With local variables, can you pass them through msg.post? I’m slightly confused on how to use it. I was thinking of passing it to my computer.script
but I don’t know if message call the book_code variable? I did read the documentation, I’m just confused about the message parameter. Yea no, reordering it wouldn’t work I think, I also just tried that.
