Help with custom skill and trait

[PKingfisher]

I am dissatisfied with the trait Deadeye from Orcs of Galaion, so I am trying to make a new version. It gives +2 trait bonus to sight-based Perception, so I want to make a new Perception (sight) skill instead of just listing a bonus.

The problem I'm having is that I want the value of Perception (sight) to include the total value of Perception. I almost have it working. I can add Perception skUser, but not skTotal, which I would prefer.

Can anyone please help.
