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.

I'm sorry it was my fault. All is good.
You are right, we forgot to edit the description: price is the optional parameter, default of it being 30.
Python instructions say each letter will cost £30, but functions is written as accepting two parameters: def billboard(name, price) .
Some test cases take a single argument and some take two, throwing an error while trying to test.
