Add State Sales Tax for a Specific State with Gravity Forms in WordPress

I’m using the advanced address field in Gravity Forms so the conditional logic option on my tax field doesn’t let me check the state in that advanced field. I can’t make the tax field only show for florida so I have to add the following javascript:

<script>
  jQuery(document).ready(function($) {
   $('#field_5_38').hide();
   $('#input_5_25_4').change(function() {
      var state = $(this).val();
       state = state.toLowerCase();
       if (state == 'fl' || state == 'florida') {
           $('#field_5_38').show();
       } else {
           $('#field_5_38').hide();
       }
   }); 
   $('#choice_30_0').change(function() {
      var state = $('#input_5_25_4').val();
       state = state.toLowerCase();
       if (state == 'fl' || state == 'florida') {
           $('#field_5_38').show();
       }
   }); 
   $('#choice_30_1').change(function() {
      var state = $('#input_5_25_4').val();
       state = state.toLowerCase();
       if (state == 'fl' || state == 'florida') {
           $('#field_5_38').show();
       }
   }); 
});
