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.

Most readable solution imho. Nice
Thanks ejini战神.
I thought I was going crazy because the "Test" always gives me an error. I made the same code for SQL but it always rejects me with a lengthy error message. Now that I know the solution is cool I'm somewhat relieved. The "Attempt" works fine but without successfully Testing first I never tried to make an attempt. I need a switch in my mindset. Always learning...always learning.
Brilliant!
