Tag Cloud

[Crick Opinion]

Hi Gurus,

I have been trying to add tag clouds to my site at http://www.CrickOpinion.com. 
I have copied the code from Template guide as below
            #set($mytags = $model.weblog.getPopularTags(-1, 30))
            <ul>
               #foreach($tag in $mytags)
                   <li><a class="tags ${tag.intensity}" 
href="$url.tag($tag.name)" title="$tag.count"> $tag.name </a>
               #end
               <br>
            </ul>

But it still doesn't generate the cloud. Any suggestions on hot achieve it.

Thanx,
