Hi,
I have a product displaying a base price and an attribute (size) having a mark-up.
Base price $100.... Attribute (Size - Large) +50
When I add to cart choosing Large size...everything works fine... showing $150.

But what I want is:
Able to showcase $150 in the drop-down attribute (instead of +50) .... and when added to cart, $150 is added.

Right now, I am able to showcase, the $150 in the drop-down, but when I add to cart, it is adding the $150 to the base price $100 making it a total of $250.

I don't want the selected attribute to add to the base-price.

Any help regarding this, would be greatly appreciated.
Thank you
