A Product Database

I have been trying to figure this out for a while now. Let me catch you guys up to speed...

I have a website that I've used WYSIWYG to put together. (I can easily understand html, but chose to use a program to save myself some time.)

I've arranged all the products on the site with the click of my mouse in WYSIWYG, along with each product page. The problem I have now is that I can't easily update the site when I have to add or remove an item.

Is there a way I can update the site, and not have to rearrange the "thumbnail" pages, it will rearrange the thumbnails automatically when the product information is removed? Also, since the site has the same layout throughout, is there a way the product pages can be put together automatically with the information provided?

The site is www.abolishskateshop.com if that helps. And by "thumbnail pages" mentioned above, heres an example:
http://www.abolishskateshop.com/Blank_Wheels.html


I wish I were able to explain this better, but I've explained it as best as I can.
Any help would be appreciated.

What you want is shopping cart software. To use a manual tool like a WYSIWYG editor means all updates will have to be manual. With a shopping cart script it is all database driven like this website/forums, everything is updated automatically.

The one I'm currently recommending is cubecart.com

Cool, I'm checking into it right now. Seems like something that I'm looking for...
