Why is the editor not recognizing my conditional?

After looking through other student's code examples and mistakes, I believe I've confirmed that my conditional is correct. I think something is wrong with the editor because it keeps telling me to check both properties, which I'm already doing. Or maybe I've missed a small, but critical detail? Any help would be appreciated.


// add code below this comment

class Subdivision {

    public $houses = array();

    public function filterHouseColor($color) {
      $output = array();
        foreach ($this-houses as $house) {
           if ($house->roof_color === $color || $house->wall_color === $color) {
              $output[] = $house;
      return $output;

Hi, you are missing a greater than symbol in your foreach condition: $this-houses. it should be like $this->houses.

good luck coding ;)

Ha! I knew I probably missed something very basic. I guess I've been staring at my screen too long. Thanks, Hossein!
