Let's say I have a product that has a base price of $80. If I add the product to the shopping cart, it shows up there just fine with the correct price.

But, if I add an attribute option with a value of +$20, the product shows up in the shopping cart with a price of $160, which is double the base price.

I've read the documention on attributes, and I think they are set up correctly, but obviously they are not...

Anyone have any thoughts on the subject?

Thanks,

Paul
