I feel summoned to declaim forum rules

Only you know what "doesn't work" means
Please tell us what your circuit or code is supposed to do and why it "doesn't work".When you come in and say "it doesn't work" or just "it has errors", that means NOTHING. There could be a million things wrong and no one will know where to look.

It's also a bit insolent to drop some lines of code without a question.
