Help with custom item power (armor)

[willuwontu]

Reduces the armor category of an armor by one step. (Heavy becomes medium, Medium becomes Light).

Phase: Pre-levels  Priority: 10000


        if (parent.tagis[ArmorClass.Medium] <> 0) then
          perform parent.delete[ArmorClass.Medium]
          perform parent.assign[ArmorClass.Light]
          perform parent.delete[ArmorCateg.Slows]

          ~adding this tag to the armor makes it count as one category worse for
          ~the purpose of proficiency, meaning it requires the same proficiency
          ~it used to.

          perform parent.assign[Helper.Prof1Step]
        elseif (parent.tagis[ArmorClass.Heavy] <> 0) then
          perform parent.delete[ArmorClass.Heavy]
          perform parent.assign[ArmorClass.Medium]

          ~adding this tag to the armor makes it count as one category worse for
          ~the purpose of proficiency, meaning it requires the same proficiency
          ~it used to.

          perform parent.assign[Helper.Prof1Step]
          endif

      ~ Add to our custom description if we're armor
      if (container.parent.tagis[component.BaseArmor] <> 0) then
        field[mtDesc].text &= " Decreased armor category and penalties."
endif

      container.parent.field[arArcFail].value -= 10
      container.parent.field[arMaxDex].value += 2
      container.parent.field[arArmorChk].value += 2

So I made essentially an item powers version of mithril (just copied the script over made a couple changes but that is it), when I select it though it says

Attempt to access field 'mtDesc' that does not exist for thing 'ipLighten'
- - -
Attempt to access field 'mtDesc' that does not exist for thing 'ipLighten'

Any Idea on what I coded wrong?

Item Powers don't have a mtDesc field, that's only on materials I believe, so you'd have to change that part. I'd just put it in the Summary.
