Can't get products to show up

Hi,
I installed Hikashop and have it in category listing mode. I setup my 2 main categories and 2 subcategories. From there I'd like to then go into products that are contained within the subcategories. Here's what my structure looks like.

Individual Messages › Audio CDs › Product here
Individual Messages › Video DVDs › Product here

Message Series › Audio CDs › Product here
Message Series › Video DVDs › Product here

So my 2 main categories are 'Individual Messages' and 'Message Series'. My 2 subcategories are 'Audio CDs' and 'Video DVDs'.

I entered product into the product section and selected which category it should go to, but then on the front end nothing shows up. Could you let me know what I am doing wrong and steer me in the right direction please.

Here's the URL of the site I am working on in case you want to take a look. www.ngfwconline.com/

Okay, I created a products module and linked it to my menu by clicking the associated module button, but now I have the product displaying on all pages. I only want it to display under each specific structure path (ex. Individual Messages › Audio CDs › Product here). How do I fix this?

I was successful! Thanks for your help on this. I really appreciate it!!!
