Attribute price not shown: impossible to know the real price of the variant (IMPORTANT FEATURE REQUEST?)

[morphinestyle]

Hello,
when i select some product attribute (image radio) that has a price difference i can't see the new price updated in real time.
In this way the buyers can't know the real price of the product attribute/variant.

I'm wrong and there is some way to show it, or this important feature is missing?

SOLVED:
I was missing a menu option to activate.
Seen just in time before building my own code in javascript...
Save a lot of time!
