function write(message) not working
<p>I'm doing the PluralSight JavaScript Fundamentals course and he enters this code into the JavaScript window of jsbin (jsbin.com)</p>

<pre><code>function write(message) {
  document.getElementById('message').innerHTML += message + '&lt;br/&gt;';
}

var streetNumber = 49;

var streetName = "Brunswick";

write(typeof streetNumber + " " + streetNumber);

write(typeof streetName + " " + streetName);
</code></pre>

<p>and when he Previews it writes out the types and values.  The video is a year old and now jsbin has a Render (not Preview) button.  When I enter the above code and Render I get a blank screen.</p>

<p>I tried pasting the code into an .html file</p>

<pre><code>&lt;!DOCTYPE html&gt;
&lt;html&gt;

&lt;head&gt;
&lt;!--&lt;meta charset=utf-8 /&gt;--&gt;
&lt;title&gt;JS Test&lt;/title&gt;

&lt;/head&gt;
&lt;body&gt;
  &lt;p id="hello"&gt;Hello World&lt;/p&gt;
&lt;script&gt;
function write(message) {
  document.getElementById('message').innerHTML += message + '&lt;br/&gt;';
}

var streetNumber = 49;

var streetName = "Brunswick"';

write(typeof streetNumber + " " + streetNumber);

write(typeof streetName + " " + streetName);

&lt;/script&gt;
&lt;/body&gt;
&lt;/html&gt;
</code></pre>

<p>and then opened the file in IE9, and the latest version of Chrome, Firefox, Safari and Opera (my OS is Win7 Ult).  They all display Hello World and nothing else.  I'm probably missing something really simple here, can someone help me out?</p>
