How to Query Posts Per Category

Hi ,

I’m trying to use query_posts function. I’m trying to filter by category. I simply just want to be able to filter and get the posts per category per geodirectory post type and use it in the loop.

A. Input Category ID.
B. Input Geodirectory Post type.

$args = (‘post_type=gd_place&cat=11’);

or

$args = array( ‘post_type’ => ‘gd_place’, ‘category’ => 11
);

query_posts($args);

1. If I include category it doesn’t work.
2. If I exclude category it will work.
3. Is there a way to properly do this for Geo Directory post types?

Thanks
