Almost there! Set a variable called "list_size" that contains the number of items in the array. You can use the "count"

I am a bit confused here. Need some help!!

array.rb 
grocery_list = ["milk", "eggs", "bread", "ice cream", "potatoes", "pie"]
first_item = grocery_list[0]
last_item = grocery_list.last
list_size = rocery_list[6]

The challenge wants you to use the count method on grocery_list instead of manually counting the number of items. You used the last method in the second challenge so follow that and use grocery_list.count.

Right now you are trying to pass the item at index 6 into list_size array. Try to use the count method.

   list_size = grocery_list.count
