I think this Kata is way too tricky (casting, format). I've given it to an apprentice to make him learn SQL (math operation in query, usage of "as", order by) but having to cast and play with format are, IMHO, not for 7kyu.

It's working again now ! Thanks @matt_c

@matt_c still get the same error, just tried again.

He he, well take your time is 1am here and I need some sleep...

@matt c it would be greatly appreciated ! Ping me if I can test something...

All tests passed but get an error:

Reinforcement Test Cases:

 TypeError: Cannot read property 'caller' of null

Any idea ?
