Yeah, there was a general CodeWars bug preventing any katas from being completed/submitted. It is fixed now, so go ahead and resubmit!

Currently Codewars platform is experiencing issues.

@sanjsanj You don't even need return. Ruby returns whatever has been processed at the end. You can just write the string.
@mjvezzani If you change areYouPlayingBanjo(name) to are_you_playing_banjo(name) in your code and in the tests as well you will be fine...

I was just about to come here to say the same thing, you can decipher it if you carefully deconstruct the error messages but it is quite confusing, especially for a beginner looking to do an 8 kyu kata :)

Also I'm doing the Ruby version and 'puts' the name didn't work either, I had to 'return' it.

description says: "Date parameter could be a string or a Date object."

Thanks for the feedback. Floats compeletly slipped my mind in this scenario. Nice catch!
