[jQuery] What am I getting this error?


Hi, all...
Why am I getting this error:
missing ; before statement
var tour-info-div = '$('this').prev('.tour-info-div')' ; \n
from this code: ???
$(document).ready(function() {        
            
$('.update_button').click(function(){
                    
var formval = { tour_url: $('this').prev('.update_input').val() ,
mls_number: $('this').prev('.tour-div-info').attr('id').val() } ;
var tour-info-div    = '$('this').prev('.tour-info-div')' ;
var update-div = '$('this').prev('.update-div')' ;                
                                    
$.ajax({ cache: false,
type: "POST",
url: "../components/virtual_tours.cfc?method=update_tour&returnFormat=json",
dataType: "json",
data: formval,
success: function(response) {
                                     
if (response.update == "Update Successful")
{ $('update-div').hide();
$('tour-info-div').load("???").show(); }
else
{ $('#unsuccessful').empty().fadeIn(500).append(response.update) };
                                             
}
    
});
});        
});
