title: jQuery animate and property values in percentage
body: <p>I trying to animate a div and I try to use some value retreived somewhere else, I know the value to be correct because I've printed out the output... so I'm wondering why doesn't it work properly?</p>
  
  <pre><code>animateBar(percentage.toFixed(2)+'%');
  
  [ . . . ]
  
  function animateBar(percentage)
  {
      $('#innerBox').animate({width: percentage}, 3000);
  }
  </code></pre>
