RE: [xsl] javascript and xsl

I have some javascript contained within my xsl sheet:

<xsl:template match="/">
<!--start html page-->
<html>
<head>
<title>Edit an Event</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"/>
<script language="JavaScript">

function MM_findObj(n, d) { //v3.0
  var p,i,x;  if(!d) d=document;
if((p=n.indexOf("?"))>0&amp;&amp;parent.frames.length) {
    d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
  if(!(x=d[n])&amp;&amp;d.all) x=d.all[n]; for
(i=0;!x&amp;&amp;i&lt;d.forms.length;i++) x=d.forms[i][n];
  for(i=0;!x&amp;&amp;d.layers&amp;&amp;i&lt;d.layers.length;i++)
x=MM_findObj(n,d.layers[i].document); return x;
}

function MM_validateForm() { //v3.0
  var i,p,q,nm,test,num,min,max,errors='',args=MM_validateForm.arguments;
  for (i=0; i&lt;(args.length-2); i+=3) { test=args[i+2];
val=MM_findObj(args[i]);
    if (val) { nm=val.name; if ((val=val.value)!="") {
      if (test.indexOf('isEmail')!=-1) { p=val.indexOf('@');
        if (p&lt;1 || p==(val.length-1)) errors+='- '+nm+' must contain an
e-mail address.\n';
      } else if (test!='R') { num = parseFloat(val);
        if (val!=''+num) errors+='- '+nm+' must contain a number.\n';
        if (test.indexOf('inRange') != -1) { p=test.indexOf(':');
          min=test.substring(8,p); max=test.substring(p+1);
          if (num&lt;min || max&lt;num) errors+='- '+nm+' must contain a
number between '+min+' and '+max+'.\n';
    } } } else if (test.charAt(0) == 'R') errors += '- '+nm+' is
required.\n'; }
  } if (errors) alert('The following error(s) occurred:\n'+errors);
  document.MM_returnValue = (errors == '');
}

</script>
</head>

<body bgcolor="#FFFFFF">
<form name="form1" method="post" action=""
onSubmit="MM_validateForm('0','','R','0','','R','0','','R','1','','R','1',''
,'R','2','','R','1','','R','city','','R','country','','R','region','','R','o
rganisation','','R');return document.MM_returnValue">
  <table width="600" cellpadding="5" cellspacing="5" border="0">
    <tr bgcolor="#FFFFFF">
      <td colspan="2" valign="top">
        <p align="left"><font face="Arial, Helvetica, sans-serif"
color="#FF6600" size="4"><b>Edit
          An Event </b></font></p>
      </td>
    </tr>

etc ......

</template>

PROBLEM:
I am using saxon and I am getting the following error:
java.lang.NullPointerException

Am I missing something?
- I have altered all & and < characters to comply with xslt notation.
- do I need to include some statement in the xsl sheet?
