Set Attribute to specific value?

[TCArknight]

Ok, I'm working on Savage Rifts, and in it the Glitter Boy Power Armor provides a strength of d12+4 (value of 9) when worn.

I'm trying this:Pretraits/5500

~Strength starts at value of 2 (d4)
var DiffStr as number
DiffStr = 7 - #trait[attrStr]

if (field[grIsEquip].value <> 0) then
   #traitcreation[attrStr] += DiffStr
   hero.child[attrStr].field[trtMaximum].value += 4
   endif

This successfully provides a strength of D12+4 if strength hasn't had any points put into it (and at a d4).

If strength is at a d6 before equipping the GB armor, Then strength becomes d12+5 when equipped. However, if it is at a d8, it still only goes up to a d12+5. At that point, when unequipped STR becomes a D6 abd there is an attribute point to spend.

Is there a used way to set an attribute to a specific value when an item is equipped?

Thoughts?
