Can someone tell me what I'm doing wrong here?

I,m supposed to add grocery_item hash to the items array inside the grocery_list hash

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

Try this instead:

grocery_list["items"].push(grocery_item)

Over here I'm getting the "items" key and pushing "grocery_item" to the end of the "items" array inside of "grocery_list".

Good luck! ~Alex

The idea of using push came to mind. I need to follow my intuition more. Thanks for your help!
