What Is The Proper Code To Call Javascript?

Hi,
For some reason, a piece of JS isn’t working anymore (it was up until a few days ago).

The JS is fine and then I call it where I want it to appear in the post (it’s a little calculator) with this

<script type=”text/javascript”>// <![CDATA[
mhspcalc();
// ]]></script>

But it’s not working any more?

Any ideas, guys?

Any help would be great.
