my animate() function doesnt work
<p>I have this code :</p>

<pre><code>&lt;script type="text/javascript" src="settings/jquery-1.5.min.js"&gt;&lt;/script&gt;
&lt;script type="text/javascript" src="settings/jquery.color.js"&gt;&lt;/script&gt;

&lt;script type="text/javascript"&gt;
    function addTrack(param) {
        $('.tracklistOff').find('.trackon').clone().insertAfter(($(param).parents('.trackon'))).animate({ backgroundColor: "#FCFCD8" },200);
    }
&lt;/script&gt;                 
</code></pre>

<p>but unfortunatly, when I call that function, I don't get the animated-color effect! </p>

<p>Instead, I get <code>cannot read property '0' of undefined</code> error. If i swap <code>backgroundColor</code> with <code>color</code> it works. What's happens?</p>
