name error with text based rpg code

[cris_ram415]

I am getting a NameError in my text based rpg and I was wondering if anyone could help. Here's the code:

def chooseCoffee ():
    coffee = ""
    while coffee != "iced coffee" and coffee != "black coffee" and coffee != "cappuccino": # input validation
        coffee = input("Choose your coffee (iced coffee, black coffee, or cappuccino): ")


    return coffee
chooseCoffee()
if(coffee == "iced coffee"):
    print('Cashier: "Iced coffee it is!"')

Here's the error I get:

Error:
    if(coffee == "iced coffee"):
NameError: name 'coffee' is not defined

My goal is to get the program to print the message "(coffee) it is!"
If there's any way you could help me, I'd really appreciate it! Thanks
