WordPress Custom Post Type Rewrite Help

Hi All,

I’m having a little difficulty with a very simple WP plugin I’ve written for group guides. You can see the code at:

The permalinks work for:

http://url.com/group-guides/
http://url.com/group-guides/specific-group-guide/

I’m unsure how to get things configured with the taxonomy group-type.

I’d like the permalink to look like this:
http://url.com/group-guides/member-guides/name-of-specific-guide/

Right now I don’t seem to have a permalink at all for the taxonomy, e.g. going to either of the following doesn’t display an archive page:
http://url.com/group-type/
http://url.com/group-guides/group-type/

Anyone familiar with WP and able to give me a hand?

Thanks,
Dave
