Unable to add Grocery Hash to Grocery_List Array (3rd item inside)

Alright, this one is really hard. I have tried this about 20 different ways over half an hour straight; also re-educated myself with the videos three times now and carefully watched the syntax, parenthesis, curly braces etc. This one is super tricky to me. I even tried defining a new method and returning the grocery hash inside the method and then pushed those two together while being aware that it has to go into the third argument of grocery_list (example: 2) as it's an array. I'm totally stumped. Any help would be appreciated. The good news is that I got through the first 3 of 4 challenges on the first try . What am I doing wrong??

shopping_list.rb 
grocery_list = { 'title' => 'Grocery List', 'items' => [] }
grocery_item = { 'title' => 'Bread', 'quantity' => 1 }
grocery_list(2).push(grocery_item())

Add the grocery_item hash to the items array inside of the grocery_list hash.

what you should do here is add the whole grocery_item hash into the grocery_list['items'] empty Array.

grocery_list['items'].push(grocery_item)

ARGH! So close! The funny thing is that I even previously tried the [brackets] several times as I knew it was an array. However, I didn't pair it correctly with the last part exactly as you have written above. Then there's the flip side to that too....at one point, I tried only the single parentheses for grocery_item but didn't get the array portion exactly right. So frustrating (sigh)....

Thanks for your help.
