Creating an SMS collection links to AD group

[armatage]

I'm trying to make a collestion in SMS 2003 that is linked to an AD group called OxfordNBSUsers. I have made the group in AD and added myself to the security group.
I then.....
1. Right click collection in SMS console and clicked new collection
2. Set the name to Oxford_NBS_Users and clicked the membership tap
3. Clicked new query button
4. Called it Oxford_NBS_Users
5. Selected User Resource in the drop down box
6. Clicked edit query statement
7. Clicked criteria and clicked new query
8. Selected simple value and pressed select
9. Selected user resource and user group name in the drop down boxes

10. Selected is equal to and types DOMAIN\Oxford_NBS_Users (where DOMAIN is the company domain)...clicked ok...ok...ok...ok
11. I updated the collection membership but the names I added to the security group don't show in the collection

We are using this method to install office 2007 std or pro but the person has left and we don't know how it was done.

The vales section in the query doesn't show the security group

Any ideas on why the users are not showing in the collection.

Once the users are in the collection I can create a package and install to these users.
