Assigning Weapons Proficiency

[BobStumpp]

I am trying to put together a feat that grants Proficiency for any Non-Heavy weapon. The code is close, but I am missing something

foreach pick in hero from BaseWep where "!wProperty.Heavy"
  if (eachpick.tagis[Helper.Proficient] = 0) then 
     perform eachpick.assign[Helper.Proficient]
  endif
nexteach

This Eval Script done in Post-Levels works mostly. Once you equip the weapon it shows as you are proficient, and grants the appropriate to hit adjustment. However, if you go to buy a weapon, the Weapons List shows that you are not proficient with some nice red text saying "Not proficient with weapon". But again, once you equip the weapon, it shows that you are proficient.

Any idea as to where/when I should be setting the Proficient tag? Or is there another tag I should be setting?

Thanks,

Bob
