Simple Tag Cloud Widget for Blogger

I've replicated the code below just in case the above link does not work. All you need to do is add a label widget and change its code to the following:

   1: <b:widget id='TagCloud' locked='false' title='Tags' type='Label'>

   2:     <b:includable id='main'>

   3:     <b:if cond='data:title'>

   4:       <h2><data:title/></h2>

   5:     </b:if>

   6:     <div class='widget-content' style='text-align: justify;'>

   7:          <script type="text/javascript">
