jQuery Error in IE7

[fanderson]

I am using the drop shadow plugin ​http://plugins.jquery.com/project/DropShadow, which works fine in Firefox but I get an error 12949 in IE7.

My code is as follows:

<script type="text/javascript"> $(document).ready(function(){

$('.main_content').dropShadow();

}); </script>

This isn't a jQuery core bug. Please post plugin help questions on one of the jQuery forums.
