Working with Attributes in PrestaShop

I have been working with PrestaShop now for over a month. One of the challenges is getting the attributes to work for the products. If you try to upload the attributes with the products in the csv file you will get a very disappointing side effect. The attributes will go to the cart all together so the store has no way of determining what attribute you are ordering. On the site I am working on we needed sizes for shirts. The sizes had different prices as well. The cart was catching the price change but put all of the sizes on the shirt not just the one size you would want to order. I figured I could just make separate categories for the product by size and crashed the whole site. Our hosting service has been working on this problem ever since. I have learned that the new php does not like having over 300 categories. My client’s site had over 1300 categories when I crashed it. I then realized I needed to get the attributes to work. I found you can import the attributes separately and they will work just fine. Then you are forced to add the attributes to every product individually and they will work the way they are supposed to. I will be putting pics up soon of this process.
