How can I sort the service providers by last name? See http://www.officials.wisconsin-web-writer.info/make-an-appointment/. If you scroll down in the service provider list you will see that it isn't alphabetical (you have to go all the way down).
If you send code, send it all please. I found a similar question and added this question to that one. (See it here: https://premium.wpmudev.org/forums/topic/edit-order-of-services-in-dropdown-menu#post-762804) However the code given creates a fatal error. I am sure I am missing something.
