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.
It works fine to me and I see many users did it, so I assume there is something wrong in your code, like an open parenthesis or something like that.
If you need further help, please comment under my post below, so that I will get notified :)
