Sure! Three times (the "Submit final" one, of course), but every time I do it I get the message "the solutions have been witheld......as you didn't solve this kata, etc etc" instead of the solutions screen. In the index of katas it's checkmarked as the rest of the katas I've solved, but something has gone wrong with this one. No big problem, anyway.

have you tried clicking the submit button

Hello! Nice kata, I've passed all the tests but when submitting it I get the same message as when you try to check solutions before solving a kata and I have the "try again" button enabled. When I search the index of regex katas for the name of this one it is checkmarked as it's solved, but again when selecting the kata the "try again" button is enabled and I get the same "you cannot unlock solutions..." message. Is it a problem with the kata or with the servers? Thanks a lot for helping
