Python Lovely Loveseats Challenge - weird "NameError" not defined - but I've defined the variable!

I’m on this Receipts For Lovely Love Seats Python challenge

Basically, I feel like I’ve done everything right but when I add this to line 23 (to calculate sales tax):

customer_one_total += customer_one_tax

I get a NameError saying that:

Traceback (most recent call last):
File “script.py”, line 23, in
customer_one_total += customer_one_tax
NameError: name ‘customer_one_total’ is not defined

What’s wrong here? I’ve defined this variable already, so why does this error appear when I add the line 23 to calculate sales tax? (No error appears when I remove line 23.) Here’s my code:

lovely_loveseat_description = "Lovely Loveseat. Tufted polyester blend on wood. 32 inches high x 40 inches wide x 30 inches deep. Red or white." lovely_loveseat_price = 254.00 stylish_settee_description = "Stylish Settee. Faux leather on birch. 29.50 inches high x 54.75 inches wide x 28 inches deep. Black." stylish_settee_price = 180.50 luxurious_lamp_description = "Luxurious Lamp. Glass and iron. 36 inches tall. Brown with cream shade." luxurious_lamp_price = 52.15 sales_tax = .088 cutomer_one_total = 0 customer_one_itemization = "" cutomer_one_total +=lovely_loveseat_price customer_one_itemization += lovely_loveseat_description cutomer_one_total +=luxurious_lamp_price customer_one_itemization += luxurious_lamp_description customer_one_tax = cutomer_one_total * sales_tax customer_one_total += customer_one_tax print("customer_one_items:") print(customer_one_itemization) print("Customer One Total:") print(cutomer_one_total)

you misspelled customer_one_total as cutomer_one_total
