Overlib popups in IE

[TenX]

Same issue as some of the other users, but cant seem to find the solution in the posts. Overlib popups work fine in Firefox but give the folowing error in Internet Explorer.
'undefined' is null or not an object
The web with this issue is http://www.pack385.org/
Thanks for the help!:classic:

I did look at the solutions posted but since I don't have much of an idea of php, I don't really get the references to the main and include files jspe377523 (http://www.easyphpcalendar.com/forums/member.php?u=3198) is refering to. Other posts refer to multiple head and body tags causing this issue also but havn't been able to find anything like that either.
