NameError: name 'total' is not defined

Hi Everyone. I have been having been struggling when it comes to finding the solution to solve the NameError: name 'total' is not defined.

This happens every time I run the check_please.py file, and unsure why that is. Would love to know the solution to this. Thank you.

Project based on splitting a check with people you go with to a restaurant

import math

def split_check(total, number_of_people):
    return math.ceil(total / number_of_people)

try:
    total_due = float(input("What is the total?  "))
    number_of_people = int(input("How many people?  "))
except ValueError:
     print("Oh no! That's not a valued value. Try again...")
else:
    amount_due = split_check(total, number_of_people)
    total = "anything you want"
    print("Each person owes ${}".format(amount_due))

treehouse:~/workspace$ python check_please.py

NameError: name 'total' is not defined

This is my result so far. Just wanted to know how where total = "anything you want" should be placed.

okay Michael, firstly when is said (total = "anything you want") is was trying to show you the syntax for declaring a varible, so I'm sorry if I confused you there. now back to your code. first remove (total = "anything you want"): It's not useful, that was just an example. now the problem with your code is ( amount_due = split_check(total, number_of_people) ) . amount_due = split_check(total_due, number_of_people) is the correct thing to do.

your parameter "number_of_people" is defined on line 8 which is correct, now the problem is the parameter "total" you didn't define that, but you have "total_due" so your first parameter should be "total_due"

I hope this helps.
