Custom template timing issue

[Minous]

I am working on the Mist-tainted template from PZOPSS0005E - Pathfinder Society Scenario 05 - Mists of Mwangi and I need to lower an ability score to 6 if its higher than that.

Setting the value is fairly straight forward:

hero.child[aCHA].field[aNormForce].value = 6

However timing and figuring out what field to use in the if statement has be pulling my hair out.

My primary code is:

if (hero.child[aCHA].field[aNormal].value >= 7 )then
  hero.child[aCHA].field[aNormForce].value = 6
endif

But I cant get the if statement to validate correctly.
