outerHeight is not a function?
<p>Having trouble with this jQuery function:</p>

<pre><code>$("#content").siblings().each(function(i){
  heightOfSiblings = heightOfSiblings + this.outerHeight();     
});
</code></pre>

<p>Error is 'outerHeight is not a function.'</p>

<p>What am I doing wrong?</p>

<p>Thanks!</p>
