Stuck on method overriding

I'm stuck with how to implement what the challenge is asking for. What can I do to fix it?

inventory.py 
class Inventory:
    def __init__(self):
        self.slots = []

    def add_item(self, item):
        self.slots.append(item)

class SortedInventory(Inventory):
    def add_item(self, item):
        super.add_item(item)

Any time you invoke (call) a method, you must put parentheses () after the method name, even if you are not passing any arguments.

Your call to "super()" is missing the parentheses.

I'm not sure what I else I can do to pass the challenge?

class Inventory:
    def __init__(self):
        self.slots = []

    def add_item(self, item):
        self.slots.append(item)

class SortedInventory(Inventory):
    def add_item(item):
        super().add_item(item)

I see you fixed the "super" call, but somehow you also lost the "self" parameter from "add_item". Put that back as you had it before and you should pass task 2.
