My shopping list is a hot mess

Hey there, so my shopping list doesn't work, and I think I messed it up trying to fix it. Anyone could help me understand what I did wrong?

Thank you! Here is the snapshot: https://w.trhou.se/iyagqkoai6

Hey Marta, looks like you misspelled some things in your add_to_list function on line 53. 

def add_to_list(new_item):
    show_list()
    if len(shopping_list):
        position = input("Where should I add {}?\n"
                         "Press ENTER to add to the end of the list\n"
                         "> ".format(new_item))
    else:
        position = 0

    try:
        position = abs(int(position))
    except ValueError:
        position = None
    if position is not None:
        shopping_list.insert(position - 1, new_item)
    else:
        shopping_list.append(new_item)

Hi! Thank you, I fixed that:) However it keeps giving me the same error...it says "item" is not defined. Although I did exactly as Kenneth did!
