'null' is null or not an Object form.js

Hi.
this error was driving me up the wall ... and thought i would share this issue ..
what it boils down to is document/website compatibility  ... :(
so by implementing the appropriate compatibility mode, a SharePoint site can ensure compatibility with Internet Explorer 8 until the service pack is release to support IE8 compatibilty issues.
