iframes and parent.document

[Crusader]

<script type="text/javascript"><!--
document = parent.document;
//--></script>

I have the above code contained in an iframe. It loads on both Firefox and Internet Explorer but it gives me an "Access Denied" error in the loading bar (bottom left hand of the screen) after the page loads on Internet Explorer.

Any ideas on how to fix this?

Thanks.

What is it being used for? Could you post the other code? :tu:

It's basically just an iFrame that loads the above code followed by Adsense code.

<iframe id="a780ee65" name="a780ee65" src="urlOfIframe.php" frameborder="0" scrolling="no" width="300" height="250"><a href="linkHere.php" target="_blank"><img src="imagehere.jpg" border="0" alt="" /></a></iframe>

urlOfIframe.php

<script type="text/javascript"><!--
document = parent.document;
//--></script>
<!-- google adsense code etc -->
