All blocks containing a certain #tag

What is wrong with my advanced query below?
(I know I can do that easily with the simple Query, but I plan on adding to it)

Edit: fixed code:

{ :title [:h2 “Blocks Tagged #person”]
:query [:find (pull ?b [*])
:where
[?p :block/name “person”]
[?b :block/refs ?p]]
}

Apparently you are using the DB version, in which one queries should be written without the #+BEGIN_QUERY and #+END_QUERY lines.

Thanks, that was it!
