title: jQuery: selecting a span with a particular id
body: <p>I'm getting an error message on this function telling me that parseInt doesn't have a radix parameter, even though I'm passing it the variable moveCount. I assume this means that the value of the span with the id #moveCount is not being assigned to the variable moveCount. I've marked the line below where I think the problem's arising. I've tried this line</p>
  
  <pre><code>moveCount = $('span #moveCount').html();
  </code></pre>
  
  <p>both with and without using the word 'span' in the selector and am getting the same result. </p>
  
  <pre><code>function incrementMoveCount() {
      //gets the html of the span with id
      //moveCount
      //turns it into a number
      //increments it by one
      //sets the html of the span with id moveCount
      //to the new move count
      var moveCount = 0; 
      var newMoveCount = 0;
      moveCount = $('span #moveCount').html();   # problem here
      newMoveCount = parseInt(moveCount);
      newMoveCount = newMoveCount + 1; 
      $('span #moveCount').html('newMoveCount');
  }
  </code></pre>
  
  <p>html</p>
  
  <pre><code>&lt;div id="meta"&gt;
  &lt;h1&gt;Checkers&lt;/h1&gt;
  &lt;h4&gt;Moves: &lt;span id="moveCount"&gt;0&lt;/span&gt;&lt;/h4&gt;
  &lt;/div&gt;
  </code></pre>
