Regarding Zybooks Introduction to Scripting, exercise 1.9: Madlib

I have worked through the exercises in the reading, and was able to complete them. I am stuck on the Madlib.

I have set up the program as:

first_name = input('enter a name: ')

generic_location = input('enter a location: ')

whole_number = input('enter a whole number: ')

plural_noun = input('enter a plural noun: ')

print(first_name, 'went to', generic_location, 'to buy', whole_number, 'different types of', plural_noun)

What am I doing wrong?
