Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.

I solved this kata, but I get an error only with the third telefon number ("(098) 123 4567"), i don't understand where is the mistake. I'm not US.
Proper regular expression setup fix
You can solve this issue with proper regular expressions
Thank you very much! It works now! I think the author should edit the kata description :)
I completed the Kata for all tests. I get an error only on "Second long text block". How is it possible?
