title: If not disabled do this
body: <p>I am adding numbers entered into some inputs and getting a total. The totaling script works however now I want to not included the inputs to be counted if they are disabled. I am thinking I need to use :not(:disabled) but not sure how to put it into my script properly?</p>
  
  <p>This is the script that counts:</p>
  
  <pre><code>$('.observationPositive').each(function(){
      countP++;
      sumP += Number($(this).val());
  });
  </code></pre>
  
  <p>How do I say only count if not disabled? (wrongly coded example)</p>
  
  <pre><code>$('.observationPositive').each(function(){
      countP++;
      sumP += Number($(this:not(:disabled)).val());
  });
  </code></pre>
