Classifieds categories return all listings...?

Hi, thanks for taking a sec.
Not sure if this is correct or not, but I'm showing the classifieds categories in the sidebar with the number of items.
However, when I click on the category, only one of the "classifieds listings" shows up on the results page.
How can I get a results page that returns all of the "listings" for that category?
Thanks so much,
Y
