<p>I am recieving an error below in IE only, not in any other browser:</p>

<pre><code>Object doesn't support property or method 'getElementsByClassName' 
</code></pre>

<p>So I am assuming it does not suppose getElementByClassName in IE. My question is then what should be an equivalent to use in stead of this in example below:</p>

<pre><code>var numb = document.getElementsByClassName('num_questions');
</code></pre>
