When I get to total my code spits out "your total is None." I'm not sure how I am getting this. Iv been following along.

TICKET_PRICE = 10

tickets_remaining = 100

def calculate_price(num_tickets): result = num_tickets * TICKET_PRICE

while tickets_remaining > 0: print("There are {} tickets remaining.".format(tickets_remaining)) name = input("What is your name?\n") number_of_tickets = (input("How many tickets would you like {}?\n".format(name))) try: number_of_tickets = int(number_of_tickets) if number_of_tickets > tickets_remaining: raise ValueError(" There are only {} tickets remaining.".format(tickets_remaining)) # Raise value error if request is for more tickets than are available except ValueError as err: #include error text in the output print("Make sure you enter a valid number and try again.{}".format(err)) else: total = calculate_price(number_of_tickets) print("{}, your total is {}.".format(name, total)) proceed = input("Would you like to proceed {}? Y or N\n".format(name)) if proceed.capitalize() == "Y": # TODO: Gather CC info print("Sold!") tickets_remaining = tickets_remaining - number_of_tickets print(tickets_remaining, "Ticket remaining.") elif tickets_remaining == 0: break else: print("Thank you anyways, {}.".format(name))

print("Sold Out!")
