```
 $(document).ready(function() {
  var modelNumber = false;
  var Description = false;

  $('#step-two-btn').click(function(e) {
    e.preventDefault();

    modelNumber = $("#model-number-field").val();
    Description = $("#description-field").val();

    alert(modelNumber); //undefined
    alert(Description); //undefined
  });

});

```

Can anyone tell me why the following variables are returning undefined? I have defined global variables but jquery does not seem to recognize them.
