[jQuery] Validation (groups, rules and messages)

[Atkinson, Sarah]

I'm working with the validation plugin
I have a first name and last name field and I want to have these grouped 
together with one message. This is what I have:
But the message still isn't showing.
                                                  groups: {        fullName: 
"firstname lastName",  },    rules:{        fullName: "required",    },    
messages:{        fullName: "Both first and last name are required",
