Custom .admx files to add search providers

[ogeccut]

This is my first post. Please tell me if i am posting in a wrong section.
I am trying to create Custom .admx file to add search provider "google".
I tried to follow this link:
How to create custom .adm or .admx files to add search providers to the toolbar search box in Internet Explorer 7
And created a file, but when i copy my files to the local machine for testing.
%windir%\policydefinitions and open gpedit i get the following error:

Encountered an error while parsing. Line 2, column 38

Here is a script that i created:
