Example task doesn't work

[Daniel]

I have done this http://spinejs.com/docs/example_tasks example over and over again and cant get it to work...
I get the error "Task" is undefined... my code is exactly that as instructed in the guide but it doesn't work, the source code that you have provided on here is not the same as the websites boasted syntax and doesn't follow the guide so I can't reference it.

Could you please either provide a accurate source for the guide on the website or update the website with a guide that either works from following it, or follows the same code as this source.

This would be much appreciated for low level Javascripters :)

Thanks very much.
