So i have followed the instructions, done a post type,

So i have followed the instructions, done a post type, a few Taxonomies and some Custom Fields. When i go to add a post under the post type, called Art, as soon as i start typing says i don't have permission, if i publish it takes me to a page where it says no permission. I followed the example and checked that all boxes have the same info? ay ideas?
Thanks
Alexei
