It looks right, but I haven't tested it. I also wouldn't use abValue for basic variable usage.

I would do something like:

var int_bonus as number
int_bonus = hero.child[aINT].field[aBonus].value
foreach pick in hero where wCategory.Firearm
       eachpick.field[dmrBonus].value += int_bonus

I will also note that the fields you are using may or may not be correct, I dont have HL handy to confirm.
