Some of our products have multiple attributes. I have set the products up to be priced by attribute with a base price of $0. The prices are based on size, which is the first set of attributes. The other set of attributes are color, there are 17 color attributes. They are all priced at $0. However, there are a couple of colors that add 10% to the overall price. So if a small is $10, medium is $20 and large is $30, then selecting one of these colors makes small $11, medium $22 and large $33 since they add 10% to the overall price depending on size.

I thought that using the price factor would do what I need but it only gives the 10% increase to the lowest price, which is $10 for a $1 increase. So even if a large is selected the price comes to $31 instead of $33. I have price factor at 0.1 and offset is 0.

Am I missing something or is there no way to do this? I think I am not understanding the price factor feature and it's function. I thought that it would increase the price by 10% depending on what the price is but it seems that it's only selecting the lowest price which is the default when something is priced by attributes.
