"object required" -- ajax in IE

Question

Hi,

I have the following code :

secondLevelElement = document.createElement('div');
if(xmlDoc.getElementsByTagName('get_updated' + i)[0].childNodes[0].nodeValue == false)
 {  
secondLevelElement.setAttribute('class', 'content disabled');
updatedDateStr = "<span class=\'red\'>Updated to: " + xmlDoc.getElementsByTagName('Updated_to' + i)[0].childNodes[0].nodeValue + "</span>";
 }
 else {
  secondLevelElement.setAttribute('class', 'content');
  updatedDateStr = "<span>Updated to: " + xmlDoc.getElementsByTagName('Updated_to' + i)[0].childNodes[0].nodeValue + "</span>";
 }

from the php that creates the xml:

<?php echo '<Updated_to'.$i.'> '.$var1['date'].'</Updated_to'.$i.'>'; ?>

the value of 'get_updated' can be 0 or 1.

in Firefox it's working. the error in IE is "object require" regarding to the last line.

thank you.
