Question on OG user roles functionality

Hi, I sent this question to Drupal forums but dint get a response. I think this group is more apprpriate for it. Based on what I read here, seems like thr OG User roles is designed to do what I'm trying to accomplish, but couldn;t get it to behave as expected. I'm pretty new to this so just might need some clarifications on how to get this working.

Basically, I want to setup certain users with permissions to submit blogs only for specific groups (not system wide).

So here's what I did.

As admin:
- I set the Blog content type's Organic groups usage to "Standard group post (typically only author may edit). No email notification."
- Created a role "Blogger" with the blog module's "edit own blog" permission checked.
- In og_user_roles module admin section, I made Blogger an assignable role for Organization_x

As group admin (user with permission to create groups content and configure member roles)
- I created a group. "Organization_X".
- Added a "User_X" to my group. This user will need permission to submit blogs to "Organization_x" only.
- I go to the Organzation_x's member list and go to "Configure member roles" and assigned the Blogger role to User_x.

When I log in as user_x, I don't see "Create Blog entry" from the Group Details block.

The only time to see the "Create Blog entry" is when I grant the system wide blogger role to the user, but that allows the user to submit blogs everywhere, which I don't want.

How do I allow user_x to only post blogs only in organzation_x? Am I missing any steps to set this up correctly?

Thanks!
