Context Path for Sections?

I'm having trouble creating a context for a new movie section. I want every time someone visits the /movies path, they see a right rail of advertising. I've tried using the direct path with the complete url and with just /movies as the path, but either way, nothing new appears.

I set a node-type condition to "movie" and ads appear on individual movie listings. I need ads to appear also on the movies landing page.

Any help?
