jQuery: Pass variable to :eq() does not work
<p>I have been trying to find out why the following lines of code do not work:</p>

<pre><code>$('#add-cloud &gt; select').change(function() {

 var selected = parseInt($('#add-cloud select option:selected').val()); 

 $("#cloud-calculator table tr:eq(selected)").css("color", "red");

});
</code></pre>

<p>If I change :eq(selected) to :eq(4) for example - works fine. How do you pass variable as an argument to :eq() ?</p>
