New category & product not showing

Hi,

I recently added a new category called Events to the MarketPress settings, then I added this product: http://nywriterscoalition.org/bookstore/2012-red-and-black-party/. For some reason it does not appear, not sure why. I can't find anything in the settings that would cause this. Another thing I want, is I don't want the Events category to appear on the main products page here: http://nywriterscoalition.org/bookstore/, is that possible?

Thanks!

Dana
