I am trying to store the `href` value in the `.mp3Logo` `div` to a variable. I want to store it by clicking on a `.startb`. The value in `musicLink` is being stored as undefined. Why?

Javascript

```
$('.startb').click(function() {
  var musicLink = $(this).siblings('.mp3Logo').attr('href');
});

```

HTML

```
<div class="audioContainer">
  <div class="audioTitle"></div>
  <div class="playerHolder">
    <div class="startb" id="startb26" rel="Audio/004_IAM_God_is_Love.mp3"><img src="dbs/images/start.png" width="40" height="40" /></div>
    <div class="flashObj" id="test26"></div>
    <div class="mp3Logo"><a href="Audio/004_IAM_God_is_Love.mp3"><img src="dbs/images/mp3_off.gif"/></a></div>
  </div>
</div>

```
