The question asks to create an array called grocery_list and to place the hash value with the "item" key in it.
I tried running this in irb and its working fine, but it doesn't get accepted in the challenge itself:
grocery_list = [] grocery_list[0] = grocery_item.values_at("item")
grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }
if grocery_item.has_value?("Bread")
grocery_item["food"] = true
end
grocery_list = []
grocery_list[0] = grocery_item.values_at("item")

"item" => "Bread",
"quantity" => 1,
"brand" => "Treehouse Bread Company" }
grocery_list = [ ]
grocery_item.each do |k, v|
grocery_list << k if k == 'item'
end
grocery_list
thats how you would input only the key into the new array. if I'm understanding the problem right.

5,062 PointsNever Mind. I realized that the values_at function returns an array So all that has to be done is to set grocery_list = grocery_item.values_at("item")
