Why can my ```first_pay``` not be defined? My ```second_pay``` works fine : The goal here is to calculate a salesperson's total pay for selling two vehicles, each one of any type. When they sell a new vehicle, they make $1,500. When they sell a used vehicle, they make a commission of 5% of the vehicle price. I have to make it prompt the salesperson to enter the type and selling price of each vehicle. Then, it should display the salesperson's total sales and total pay. I am not understanding what could be wrong with ```first_pay```

```firstType = input('What is the first type of vehicle you are selling? ')
firstPrice = int(input('What is the price of the first vehicle? '))
secondType = input('What is second type of vehicle you are selling? ')
secondPrice = int(input('What is the price of the second vehicle? '))

if firstType == 'new':
	first_pay = 1500
elif firstType == 'used':
	first_pay = firstPrice * .05

if secondType == 'new':
	second_pay = 1500
elif secondType == 'used':
	second_pay = secondPrice * .05

	totalPay = first_pay + second_pay
	totalSales = firstPrice + secondPrice
	print('Total sales: $', format(totalSales, ',.2f'), sep='')
	print('Total pay: $', format(totalPay, ',.2f'), sep='')
