Almost there! :)

None is a singleton, not a type; you don't need to check
type(author_brand) but rather its identity. Use "author_brand is not
None" for your condition and it should work like you're expecting. In
this case, you can actually just use "author_brand" as your condition
(no quotes, of course), as None evaluates as false.
