"Try again!" That's all I get...

I've defined the methods need in order to push the hash value to the array correct?

shopping_list.rb 
def create_list
grocery_list = { 'title' => 'Grocery List', 'items' => [] }
end
def list_item
grocery_item = { 'title' => 'Bread', 'quantity' => 1 }
end

list = create_list()
list['items'].push(list_item())

That's a pretty cool solution. You look like you studied a functional-based programming paradigm.

The way the tests are written is simpler; it depends upon the mutable nature of the list inside the hash.

You simply want to add the grocery_item to the end of the items array contained in grocery_list

Try this piece of code. Good luck on your Ruby journey it's a cool language!

grocery_list = { 'title' => 'Grocery List', 'items' => [] }
grocery_item = { 'title' => 'Bread', 'quantity' => 1 }

grocery_list['items'].push(grocery_item)
