Ok, going to try and be as clear as possible:

I have an item that comes in 4 sizes, each priced accoring to size.
So far so good, I've no problem in setting that attribute up.

But now, as for color options. I'd like to be able to set, say Chrome & Mirror Gold at +50% over the price of the regular colors.

So that if a customer wants a 12 inch decal in chrome the color attribute will reflect a 50% increase over the price set by the size attribute.

So far I've been able to pull off %50 (setting the Price Factor to 1.5) but it's calculating the new price based on the lowest size price (priced by attribute) and not the selected larger decal... I hope this was in any way clear.

Question: Is it possible to do this. I've read this entire thread (have it printed out in fact) but I haven't been able to solve this one.

Anyone willing to help a poor right-brainer here?
