I have only now become aware of price-factor and offset. I don't know if I have overlooked it for a year or two, or if it wasn't there in the previous versions. (not important enough for me to check at this instant)
What I want is to have an item priced by attribute, then have another attribute that has a price-factor of 1.1 and offset of 1 (10% upcharge).
My problem is that it is calculating the factor from the lowest priced attribute.
Is there a way of making it factor according to the selected attribute?
(I'm figuring it would probably need javascript in the tpl and a change to some function.)
Any ideas?
