Eu tenho um formulário onde eu quero ser capaz de duplicar um grupo de campos quantas vezes eu quiser. E eu também quero ter campoid, namee rótulofor os atributos desses novos grupos de campos aumentam em 1. Eu tentei isso até agora com jQuery, e consegui que pelo menos duplicasse o grupo de campos, mas remover não funciona. E não sei como fazer +1 para cada um desses três atributos. Eu aprecio qualquer ajuda que eu possa conseguir.

Aqui está um jsfiddle disso,http://jsfiddle.net/Unfxn/

// Add a new repeating section
$('.addFight').click(function(){

    lastRepeatingGroup.clone().insertAfter(lastRepeatingGroup);
    return false;
});
// Delete a repeating section
$('.deleteFight').click(function(){
