Fix Wordpress Geomashup Plugin(Javascript Error IE)

I have website made with wordpress and I used a plugin geomashup(by dylan kkuhn)to show a global map of Google Maps in a page -[login to view URL] The map it's displays fine in all browsers except in Internet Explorer 6, that gives back an error "Geomashup is undefined". I need to fix plugin so that it is possible also to be displayed in Internet Explorer 6. Here is a screenshot of my Internet Explorer Window. The URL Page is : [login to view URL] Script Error Informations: ==================== OS Information: Microsoft Windows XP Professional Service Pack 3 (Build 2600) OS Language: es Browser: Microsoft Internet Explorer 4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; InfoPath.2; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022) ;SP3; Web Browser Language: es User Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; InfoPath.2; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022) Cookies enabled Java enabled ------------- Script Error: //---------------- Line: 1364 Character: 62 Code: 0 Error Message: Object doesn't support this property or method URL: [login to view URL];width=510&height=600&show_future=false&width=510&add_overview_control=0&add_map_type_control=1&map_type=G_SATELLITE_MAP&auto_open_info_window=1 //---------------- Somebody can do it?
