stuck on a challenge task on Arrays

I'm stuck on the 2nd part of the challenge task. Stuck and kinda lost on what is the right approach. I would love it if you could explain what i did wrong a why.

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

grocery_item.has_value?("Bread")

grocery_item["food"] = true

grocery_list.values_at(grocery_item) = "item"

Hi Mustafa,

You're nearly there.

The first part is straightforward enough. if the has_value? method returns true, add to the hash:

grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }
grocery_item["food"] = true if grocery_item.has_value?("Bread")

Next you want to assign the value associated with "item" to a variable called grocery_list. Call the values_at method on grocery_item and pass the parameter "item" - assign the result to grocery_list. 

grocery_list = grocery_item.values_at("item")

I hope that helps,

Steve.
