How to send a Raphael element .toBack()
<p>Can I use jQuery to send a Raphael element by class back, like sending something back to z-index=0:</p>

<p>Several Raphael elements class="dot20" need all to be sent back</p>

<pre><code>j=2
jj = "c"+j*10
$("."+jj).toBack();
</code></pre>

<p>I get the following  error from the FF Firebug:
$("." + jj).toBack is not a function
[Break On This Error] $("."+jj).toBack();  </p>

<p>The above does not work.  Do I need some squiggly brackets?  </p>

<p>I'm lost</p>

<p>TIA</p>

<p>Dennis </p>
