Your address field has a trailing new line character (the end of your input line), you need to remove it with the chomp function. It would be actually be two characters, new line and carriage return, if your file was built under Windows, but chomp will take care of that (the exception being with a mix of 2 OSes, for example if wou created your file under Windows and use it under Unix, in which case a regular expression will be needed).
