Help needed coding a campaign trait.

[ultodrago]

So I'm trying to make a campaign trait for a home campaign that does the following:
1) Give +1 to Knowledge (History).
2) Give +1 to another Knowledge skill of the user's choice.
3) Give +1 to a Lore skill of the user's choice.

By replicating something similar to what's done in the Bandit (River Kingdoms) trait, I can get 1 and 2 working easily, but 3 can't be done with the current implementation.

I've tried multiple methods of getting step 3 to work, all which either don't work and just grab the first dropdown, or throw a compiler error.

I have scrapped the code I used prior, so I don't have anything to show. Is there a way to read from more than one drop-down selector?
