Hi James,

To show/hide fields outside of a table (based on values inside a table), you need to use JavaScript. If you give your upload button the "upload" class, your explanation field the "explain" class, and the yes/no column field the "receipt" class, the following code should do the trick:

$(document).ready(function(){
  $('.upload, .explain').hide();
  $(document).on('change', '.receipt', function(){
    $('.upload, .explain').hide();
    $('.receipt input:checked').each(function(){
      if ($(this).val() == 'Yes'){$('.upload').show();}
      else if ($(this).val() == 'No'){$('.explain').show();}
    });
  });
});

I assumed you are using a Radio Button for the "receipt" field. If not, you will need to change the selector on line 5.

Let me know if this works for you!
