IE Problem with JavaScript

My code works in Firefox, Safari, and Opera, but not IE

I am trying to display a flash advertisement using JavaScript. Everything works fine in Firefox, Safari, and Opera, but when you try to view it using Internet Explorer, nothing shows up (of course). I've tried inserting the JavaScript code into the HTML, using the JavaScript code in an external file and I've taken the HTML coding out of the document.write statements and placed it into the HTML code, but that didn't work either. I was wondering if anybody could spot something that's wrong with this code:

<script type="text/javascript">
document.write ('<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0" width="300" height="250" hspace="0" vspace="0"> \n');
document.write ('<param name="movie" value="http://example.com/MR_Property_Rotation.swf');
document.write ('?clickTag=http://example.com?http://www.example.com/property.asp?id_property=121391');
document.write ('&clickTag1=http://example.com?http://www.example.com/property.asp?id_property=121391');
