Can someone help me with this code? I'm somewhat lost!

why is it telling me this? Make sure you add a return value to the detailsKitchen method.

I'm pretty sure that's what I did. Did I pass the parameters incorrectly?

index.php 
<?php

class Render {

  public static function displayDimensions($size)
  {
    return $size[0] . " x " . $size[1];
  }

  public static function getDimensions($room)
  {
    return $size->room;
  }

    public static function detailsKitchen($room)
    {
return self::getDimensions($room);
    }
}

following code passes:

<?php
class Render {
    public static function  displayDimensions($size)
    {
      return "{$size[0]} x {$size[1]}"; //odd syntax, but just concatenation
    }
  public static function detailsKitchen($room){
    return "Kitchen Dimensions: ". self::displayDimensions($room->getDimensions());
  }
}
?>

The key feature is that you are meant to call getDimensions on the room variable, which is an object.

Simon, Thank you. But could you please elaborate why what I did was wrong? I would really appreciate it.

The problem was that you are meant to call getDimensions on $room. The room object is of a class that has a getDimensions method already defined. It returns an array, which is used as the argument for the static displayDimensions method. And you need to concatenate with "Kitchen Dimensions: " to produce the requested string.
