"Object doesn't support this property or method" error during AJAX call occurs only in IE?

During an AJAX call I get the dreaded "Object doesn't support this property or method." error.  The odd things is that I don't get this message in FireFox or any other browser, I only receive it in IE (I am using IE7).

Using FireFox and the FireBug toolbar, I see that my AJAX call is made successfully, all parameters are sent and received, and the HTML result set is updated on screen.

I've read that if the IDs of the <form> or <div> tags are the same that this may cause this error.

I can confirm by looking at the generated source code that none of the IDs for any of the <form> or <div> tags are duplicated. I have eliminated duplicate <form> or <div> IDs by using PHP to dynamically name each <form> and <div> element.

Additional Info - I am using the prototype js library to facilitate my AJAX requests.
Additional Info - I have been able to get other AJAX request to work in IE on the same site.

Can someone help me figure this out?

My js:

favorite = function(form_name, div_name){ // Updates the contents of a div             
  var url = 'scripts/update.php';
  var form = $(form_name);
  var input = form['site'];
  var input2 = form['report_name'];
  var input3 = form['user_nuid'];
  var input4 = form['add_delete'];
  var input5 = form['div_id'];
  var input6 = form['favorite'];
  var pars={action:'favorite', site:$(input).getValue(), report_name:$(input2).getValue(), user_nuid:$(input3).getValue(), add_delete:$(input4).getValue(), div_id:$(input5).getValue(), favorite:$(input6).getValue()};
  new Ajax.Updater(div_name, url, {method:'get', parameters: pars});

My PHP code which dynamically generates my forms:

while($show_it = mysql_fetch_array($get_it_query)){
if($style == 1){$tclass = "row1"; $style = 0;}
else{$tclass = "row2"; $style = 1;}
echo'<div id="favorite'.$show_it['id'].'" style="width:600px;">						
	<div align="center" style="width:45%; float:left;" class="'.$tclass.'">
	<a href="controller_download.php?cmd=file&id='.$show_it['id'].'&nuid='.$user.'" title="Download">'.$show_it['Name'].'</a>
	<div align="center" style="width:15%; float:left;" class="'.$tclass.'">'.$show_it['Month'].'</div>
	<div align="center" style="width:8%; float:left;" class="'.$tclass.'">'.$show_it['Year'].'</div>
	<div align="center" style="width:8%; float:left;" class="'.$tclass.'">
		<form id="favorite_form'.$show_it['id'].'" method="post">
			<input name="site" type="hidden" value="finance" />
			<input name="report_name" type="hidden" value="'.$show_it['Name'].'" />
			<input name="user_nuid" type="hidden" value="'.$user.'" />
			<input name="div_id" type="hidden" value="'.$show_it['id'].'" />
			<input name="favorite" type="hidden" value="1" />
			<input name="add_delete" type="hidden" value="delete" />
			<img onclick="favorite(\'favorite_form'.$show_it['id'].'\', \'favorite'.$show_it['id'].'\')" title="Remove the '.$show_it['Name'].' report from Your Favorites"  src="images/remove.png" border="0" style="cursor:pointer;" />';
