I am currently working on a form that if the user selects an option either yes or no two other drop downs are to match. I am having some trouble trying to set the values identically to each other. Here is a block of my code which checks this:

$(document).ready(function () {
    $('#Field3').change(function () {
      var isDifferent = $('.isDifferent').find(':selected').val();
      var jobOne = $('.jobClassOne').find(':selected').val();
      var jobTwo = $('.jobClassTwo').find(':selected').val();
      	if(isDifferent == "No")
        {
          $('.jobClassTwo').val($('.jobClassOne').find(':selected').val()).attr("selected", "selected");
          //document.write("<p>Have a nice day!</p>");
        }      	
    });
});

 The document.write was only to be used to test if the branch was successful.

Edit:

The two fields that need to match are jobOne and jobTwo.
