Function is not defined though js file reference is in header
<p>I am working on a page on a website (see <a href="http://www.quick-conversions.com/currency" rel="nofollow">http://www.quick-conversions.com/currency</a>).</p>

<p>I am attaching a <code>onkeyup="doConversion('...')</code> on each input field. The corresponding function is defined in a javascript file available at: <a href="http://www.quick-conversions.com/sites/MyScripts/PHP/currency.js" rel="nofollow">http://www.quick-conversions.com/sites/MyScripts/PHP/currency.js</a></p>

<p>In the source page, this file seems to be imported properly in the header:</p>

<pre><code>&lt;script type="text/javascript"
src="http://www.quick-conversions.com/sites/MyScripts/PHP/currency.js?m4xpzi"&gt;&lt;/script&gt;
</code></pre>

<p>But the function is not fired and Firebug says that it is not defined? I am running out of ideas to solve this issue. Anyone has an idea of what is happening? Thanks.</p>
