title: Jquery concatenting very simple counter with a Variable
body: <p>Following another question, I have a working script to create dynamic form fields : <a href="http://jsfiddle.net/obmerk99/uZuWA/4/" rel="nofollow">FIDDLE</a></p>
  
  <p>I thought I will figure out the rest, but I do not understand why when I try to assign a new <code>name</code> and <code>ID</code> attributes to the <code>textarea</code>, it gives me <code>NAN</code>.</p>
  
  <p>IF I do : </p>
  
  <pre><code>i++;
   var newname = jQuery(prevDiv).attr('name');    
  prevDiv.find('textarea').attr('name',i );
  </code></pre>
  
  <p>It sets ok,  But If I try to do : </p>
  
  <pre><code>prevDiv.find('textarea').attr('name',newname +i );
  </code></pre>
  
  <p>..which is what I need - I get <code>NAN</code>. </p>
  
  <p>I know my JS qualities are very close to zero, but is my syntax wrong ?</p>
