Sizzle Selector Engine Error
<p>I'm attempting to use jQuery and ASP.NET.  I am pasting the server control "ClientID" into a jQuery selector and I'm getting an error (with no error text) from the Sizzle selector engine.</p>

<p>My selector looks like this...</p>

<pre><code>$('#ctl00_ContentPlaceHolder1__phProfileHeader__filProfileImage')
</code></pre>

<p>Is it the length that might be causing the problem? I've re-checked the control ID several times in the client code and everything seems fine.  So what's the deal? I use the same strategy in several other places and they work fine.</p>
