Could you point us to the ready-made code and/or the tutorial? If Google translate is modifying your code you can see how that would create even more issues. We can’t see your code we see what translate felt like translating it to.
So I’ll suggest that you translate the text of your message but avoid putting your code through the translator.
If you look at your screenshot above (it shouldn’t have gone thru translation) you will see you are setting the content to “lowercase” and comparing it to “Hi” which clearly has a capital letter. This means they can never be equal.
You are pasting tiny snippets as well so we’re stuck wondering why you used a string like “everyone” originally. If that is in the tutorial it is seemingly a mistake. My feeling is if you copy some ready-made code from a tutorial it should work. If it doesn’t I tend to contact the author of the tutorial as they ought to know what they meant when they used a string where a bitfield is required.
You can see nobody is not interested in helping you don’t supply enough information and seemingly get a little annoyed when we don’t just fix it. Who is the original author of that code? Perhaps there are fixes posted.
