I'm just trying to figure out how to create an index inside a function so I can keep track of the items its generating and I'm not sure how to do this seems like I should know this..

addLocation(options,location)

   funciton addLocation(options,location){
       $('#list').append('<li class="location"><div>'+location.label+'</div>'+
        '<input type="hidden" name="location['+x+'][lat]" value="'+location.lat+'" />'+
        '<input type="hidden" name="location['+x+'][lon]" value="'+location.lon+'" />'+
        '<input type="hidden" name="location['+x+'][loc]" value="'+location.loc+'" />'+
        '<input type="hidden" name="location['+x+'][label]" value="'+location.label+'" />'+
    '</li>');
   }

now normally you have a forloop to help you keep track of things but int this instance I'm not appending items in a loop and I keep getting an error saying x in undefined

appreciate any help you can give

thanks Mike
