View not showing

I have a view I created for the top-level (parent) category. I have a separate view for sub-categories that is working fine. This view works fine when you click "view" under views (to see if it works right). When I go the url I specify for the view, it doesn't work right (my-gallery-shop):

The URL in the browser looks like: http://www.whatever/catalog/my-gallery-shop. The listing in the nav (on the left) shows "My Gallery Shop" at the parent, and all of the subcategories expanded. Click on any subcategory, and you get an apporpriate view (not listed here). Click on the top "parent", and you get a blank page (with only the navigation and other page stuff - just no view).

What am I doing wrong?

Thanks for any help - this is really driving me nuts.
