javascript- variable question - in XSL document

I have a javascript function in an XSL page, and can't get the beast to
handle it's own variable.
- Is there something about being in an xsl doc that buggers javascript? The
below code will  simply output 'varNow' in the URL string, instead of it's
decalred value of 'testText'..

Am I crazy? Or at least can someone can illuminate my ignorance?

----------------------------------------------------------------------------

<script language="javascript">
  function getPL(form) {
    if (form.rptPeriod[0].selected) {
        varNow = "testText";
        
window.open('http://192.168.1.13/OnePointBPO/popup.cfm?selectAcct=varNow',
'Popup',

'alwaysRaised=yes,resizable=no,scrollbars=no,height=200,width=200');
     } else {
        dateForm.submit();
     }
        return true;
     }
</script>
