I've scanned everything for typos, forgotten semicolons etc. Maybe I'm just blind? I'm not sure what's wrong.

Now I'm not completely sure what was wrong... but I removed both fill methods and then restarted the video and followed along again and now it's perfectly fine...

you must have added some extra curly braces at the end of the code. Go up to the end of the code and see if there are any xtra braces. hope it works.
