Make items in cart disappear from catalog

[vintageshop]

Hello all,

Okay, so I've seen other discussions in this area, but I have read those threads and not found any fixes that work. I'm a new zen cart user and I'm trying to get this set up for me shop selling one of a kind items. Which means each item should disappear from the catalog when added to the cart. I don't want it to as sold out, I would prefer it to simply disappear. Site is below, I have a few test items in the jackets/crested category. I hope to eventually set it so that when you go to jackets it displays all of the items in the subcategories. I've seen some threads about that, but I haven't had time to try to apply them. Still not sure why that setting for showing subcategories didn't become a setting in the admin panel.

Here is a link to my site:

It's been an uphill battle in my mind getting this set up. I feel that I'm getting close, but every time I open a new module I find a new error that needs to be fixed or tweaked. This problem with items not disappearing happens in the classic and my custom template. Any help is appreciated!

Cheers,
Christopher
