Python: Build a Movie Ticket Booking Calculator issue

Hi, I am trying to learn Python and am Step 20 of the Build a Movie Ticket Booking Calculator, and it won’t let me continue. It says that I am not putting print(‘Service charges: ‘:, service_charges below the if…elif…else statement, but I am. This is what I have at the bottom of the code:

if age >= 21 or age >= 18 and (show_time != ‘Evening’ or is_member):        print('Ticket booking condition satisfied')

    service_charges = 0

    if seat_type == ‘Permium’:

        service_charges = 5

    elif seat_type == ‘Gold’:

        service_charges = 3

    else:

        service_charges = 1

    print(‘Service charges: ‘, service_charges)

else:

    print(‘Ticket booking failed due to restrictions’)

could it be that typos are making so that your code is not recognised?

the other thing you need to check is spaces in the string
