Hello all,

I just started as a web developer and I'm particularly interested in
publishing some of my math related content on the web, so therefore I
'use' MathML in combination with XHTML. So far the rendering of
formulas is working in both FF and IE, but now when I want to execute
a JavaScript as part of a web page that contains formulas in FF, it
doesn't work while it does work in IE8 (albeit not entirely correct).
I don't see why. Can someone help me out here? I allow execution of
JavaScript in the browser so that'snot the problem at least... I think
it has something to do with my code, but I'm not sure... Here it is:

(Example Code):

<?xml version="1.0"?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1 plus MathML 2.0//EN"
               "http://www.w3.org/TR/MathML2/dtd/xhtml-math11-f.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">

<head> <title>XTHML with MATHML</title> </head>

<body>

<p>
   <math xmlns='http://www.w3.org/1998/Math/MathML'>
    <mrow>
    <munderover>
      <mo>&sum;</mo>
      <mrow>
        <mi>t</mi>
        <mo>=</mo>
        <mn>0</mn>
      </mrow>
      <mn>10</mn>
    </munderover>
    <mrow>
      <mfenced open = '(' close = ')'>
        <mfrac bevelled='true'>
          <mrow>
            <mo stretchy='false'>(</mo>
            <mn>4</mn>
            <mo>&times;</mo>
            <mi>t</mi>
            <mo stretchy='false'>)</mo>
          </mrow>
          <msup>
            <mi>t</mi>
            <mn>2</mn>
          </msup>
        </mfrac>
      </mfenced>
    </mrow>
  </mrow>
</math>

</p>

<p>

<script type="text/javascript">

now = new Date();

localtime = now.toString();
utctime = now.toGMTString();

document.write("<b>Local time:</b> " + localtime + "<br/>");
document.write("<b>UTC time:</b> " + utctime + "<br/>");

hours = now.getHours();
mins = now.getMinutes();
secs = now.getSeconds();
document.write("<h1>" + hours + ":" + mins + ":" + secs + "</h1>");

</script>

</p>

Thanks in advance for any comments,
