garchomp vs. dual weakness

[ableycp78]

Mysterious Treasures Garchomp lv. 66


Pokebody Rainbow Scale

if an active pokemon has weakness to any of the types of energy attached to garchomp, garchomps attacks do 40 more damage to that pokemon.....




if a pokemon ((Shiftry ex)) has dual weakness does garchamps attacks do 80 more damage. (just like dual weakness).?!?
(assuming that it had both types of energy according to the defending pokemons weakness)


((I ruled yes, but would like the clarification for the future))

Thanks

It doesn't stack.
It will add 40 only once.
