Using the values_at method, create an array called grocery_list with the value of the grocery_item hash at the "item" ke

a

hash.rb 
grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }
grocery_list = {"item" => "grocery_item"}
if grocery_item.has_value?("Bread")
  grocery_item.store("food" ,true)
end
grocery_list.values_at("item")

Almost, you need to call the push() method and then assign it using the values_at() method of the grocery_item to the key item. 

grocery_list.push(grocery_item.values_at("item"))

Here is my code but once I put in the line of code like you have it tells me this: "Oops! It looks like Task 1 is no longer passing."

grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }

grocery_item.has_value?("Bread")
grocery_item["food"] = true                #adds the key "food" to the hash with a value of True

grocery_list.push(grocery_item.values_at("item"))

I even tried it with the asker's code with your code. Still says the same thing.

grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }
grocery_list = {"item" => "grocery_item"}
if grocery_item.has_value?("Bread")
  grocery_item.store("food" ,true)
end
grocery_list.push(grocery_item.values_at("item"))

I think I had a different bit of code at the top for my original answer to work, here is an updated solution that will work based on what you have for your code:

grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }

grocery_list = {"item" => "grocery_item"}

if grocery_item.has_value?("Bread")
  grocery_item.store("food" ,true)
end

grocery_list = grocery_item.values_at("item")

Awesome! That worked. Do you know why my previous code wouldn't work by chance?

The first set of code needed the if block and the second one, I think it was how I structured grocery list when I was going back to answer the question, I think I had it set as an array instead of a hash, which is why push would have worked.

It was my mistake for not pasting all of my working code.
