I'm trying to create a fairly simple address book, and everything works until I try to search for a contact in my address book. I decided not to code inputing the address and telephone number until I have the program working properly.

When I select the option to find contacts, something weird happens.

For instance, if 1 record has john doe, and another has jane doe, and I try to find all people w/ last name doe, what prints out is:

doe doe

jane doe

when it should be:

john doe
jane doe
