There are three seating categories at a stadium. For a softball game, Class A seats cost \$15, Class B seats cost \$12, and Class C seats cost \$9. Write a program (using functions) that asks how many tickets for each class of seats were sold, and then displays the amount of income generated from ticket sales.

This is what i have so far but it wont run :(.

Python
```def main ( ) :
intro ( )
calculatedsales ( )

#this function prints welcome to the ticket sales program the cost of each seat is as follows ect
def intro ( ) :
print ("welcome to the ticket sales program")
print ("the cost of each seat is as follows, seat a=15, seat b=12, seat c=9")

#this function prompts the user to input each sections sales and returns each value.
section_a = int ( input ( "how many tickets sold for section a=")
section_b = int ( input ( "how many tickets sold for section b=")
section_c = int ( input ( "how many tickets sold for section c=")
return (section_a,section_b,section_c)

def calculatedsales (section_a, section_b, section_c) :
sales_a = section_a*15
sales_b = section_b*12
sales_c = section_c*9
total_sales = sales_a + sales_b + sales_c
print ("total sales = {0:.2f}".format(total_sales)

main()```

running the program:

welcome to the ticket sales program
the cost of each seat is as follows, seat a=15, seat b=12, seat c=9
how many tickets sold for section a=2 (i inputed these values)
how many tickets sold for section b=3
how many tickets sold for section c=1

saying "but it wont run" is as useful to anyone who may be able to help you, as t*ts on a bull - you need to describe what actually happens - do you get an error message, an exception, a bad answer, does the program stop on line x, etc - please update your question with any more pertinent info you have

sorry first time on this site, really appreciate you getting back to me. I just updated it with the error message. please let me know if the error message is enough to help me out or if i need to add more information. Thanks a bunch.

## Solution 1

In your main method, you call `calculatedsales()` without arguments, but that function expects three arguments. I assume you want to pass the inputted values to that function. In that case, try this:
Python
```def main():
intro()
calculatedsales(section_a, section_b, section_c)```

Also, there are some syntax and indentation errors in your code: Python has strict indentation rules, and there are also some missing parentheses in the code. Here is the code with the TypeError fixed and with correct syntax and indentation:
Python
```def main():
intro()
calculatedsales(section_a, section_b, section_c)

#this function prints welcome to the ticket sales program the cost of each seat is as follows ect
def intro():
print("welcome to the ticket sales program")
print("the cost of each seat is as follows, seat a=15, seat b=12, seat c=9")

#this function prompts the user to input each sections sales and returns each value.
section_a = int(input("how many tickets sold for section a="))
section_b = int(input("how many tickets sold for section b="))
section_c = int(input("how many tickets sold for section c="))
return (section_a,section_b,section_c)

def calculatedsales(section_a, section_b, section_c):
sales_a = section_a*15
sales_b = section_b*12
sales_c = section_c*9
total_sales = sales_a + sales_b + sales_c
print("total sales = {0:.2f}".format(total_sales))

main()```
