title: Clear input when data is entered into another input
body: <p>I have a form with a secondary address section. In this section you can fill in either Street or PO box address. I want to ensure that only one address is submitted so I want to clear the other form if a user enters data into the other input field.</p>
  
  <p>My code below is not working, any ideas? Thanks</p>
  
  <pre><code>$('#pobox_number').change(function() {
  if ($(this).val().length &gt; 0) {
      $('#street_name_postal').val('');
  }
  </code></pre>
