object.style.height doesn't work
<p>I've googled this but didn't find an answer, this is strange.  In Javascript in Firefox when I do object.style.height it doesn't return anything.  Would anybody know why?</p>

<p>In CSS I've put</p>

<pre><code>#movable {
height: 100px;
....
</code></pre>

<p>In HTML I've put</p>

<pre><code>&lt;div id="movable"&gt;&amp;nbsp;&lt;/div&gt;
</code></pre>

<p>And in JS:</p>

<pre><code>alert(movable.style.height);
</code></pre>
