My code is not working and I can't figure out why when I call my function add_to_list is not showing the message

#Create a new empty list named shopping_list
shopping_list = []


#Create a function named add_to_list that declares a parameter named item 
def add_to_list(item):
    #Add the item to the list 
    shopping_list.append(item)
    #Notify user that the item was added and state the number of items in the list currently
    print("The item was added to the list,There currently are",len(shopping_list))


def show_help():
    print("What should we pick up at the store?:")
    print("""
Enter 'DONE' to stop adding items.
Enter 'HELP' for this help.
""")

show_help()
while True:
    new_item = input("> ")


    if new_item ==  'DONE':
        break

    elif new_item == 'HELP':
        show_help()

    continue 

    #call add_to_list with new_item as an argument 
add_to_list(new_list)

Okay, so you've got the right idea but there are a couple of minor issues. 

while True:
    new_item = input("> ")

    if new_item ==  'DONE':
        break

    elif new_item == 'HELP':
        show_help()

    continue # You don't need this here. Try using else instead.

# There is no new_list variable. You'll want to be using the new_item you just got.
add_to_list(new_list) # This line is also not currently tabbed into your loop.

Correcting those two things should get your code behaving as expected. But if you get stuck, please let me know and I'm happy to answer questions or walk through a solution with you.

Happy coding!
