Can’t get program to run properly

I merged the other thread into this one. Don't post same thread in multiple sub-forums

1. Look at line 18. Is that really what you meant?
2. You call get_customer_info() but that function doesn't return anything.
3. letter() is never called
4. Unclear from your logic structure - is get_customer_info supposed to get one customer's data or is it to loop through all the customers before returning. Currently it really doesn't do either properly. If called repeatedly it will only return the first customer.
