Facebook FQL Query (#601) Parser error: unexpected '#' at position 58

it's the first time I'm not able to find a solution for an error on my own. I try to perform a fql query but I', getting a very strange response :/

FQL:

{
  "477215715631180":
      "SELECT name, start_time, location, creator, pic_square 
       FROM event WHERE eid=477215715631180",
  "creator_477215715631180":
      "SELECT name FROM profile WHERE id IN (SELECT creator FROM #477215715631180)"
 }

Response:

(#601) Parser error: unexpected '#' at position 58.

Position 58:

... FROM event WHERE ...

API Explorer.

Is there anybody with a solution?
