I know I'm a little late to the party here, but I have a question in regards to adding this coding. How would I get it to apply to the individual variations on a product?

An example - I have two versions of the same product but one is Standard Edition (weighs 13oz) and the other is a Special Edition (weighs 1lb 6oz because of bonus material). I want to be able to display those weights in the different weights (lbs & oz) but when I add this code it only applies it to the main shipping place and not on the variations.

Any suggestions are welcome. :) Thank you.
