**Example:**
<http://jsfiddle.net/dfcyb/>

I have these two vars

```
var inview = '#' + $("#container > .section > h1:in-viewport:first").parent().attr('id');
var $link = $('#menu a').filter('a[hash=' + inview + ']');

```

**inview** checks to see if a particular section is in the viewport and then using the **$link** var to add a class. I'm not sure what I'm doing wrong here. Inview is working fine but:

```
$link.parent().addClass('selected');

```

does nothing. I'm not really sure what I have wrong here or how to go about debugging since console.log($link) isn't helpful. I'm not sure if filter is being used right here?
