It means how are you
Hi, that is written incorrectly. It should be ¿Cómo está usted?. It means ''How are you?"
IT MEANS that the person that is talking to you is asking you about your whole being status. The translation will be how are you?
You have mixed the informal and formal forms into the same sentence. Either say, "Como estas?" (informal form) or say, "Como esta usted?" (formal form). Both mean "How are you?"
