The "issue" tag is for problems with the kata, not problems you're having solving it. This is a problem in your code. Please use the "question" tag instead in the future unless you're very, very certain that the kata itself is broken.

In either case please provide more information. "Doesn't work" isn't enough info to help you with either kata issues or questions. What are you seeing, and how does it differ from what you expect? Remember to also use a spoiler tag if you're posting complete or partial solutions.

that's a bold statement. can you prove it?
