Hi, maybe there is something about attributes I just don't get. I would appreciate some help figuring out what I need to do.

I am setting up attributes for different sizes of products. Eg, I have an oil that comes in 100 ml, 500ml and 1000 ml size. Rather than make my customer free form in a size, I would like to put in the different sizes as attributes.

As you can can imagine each of these sizes have different weights and dimentions.

How do I set up my attributes with the right size and weights? Is that possible?

Thanks, Pat
