I've managed to get the script working.

~ Add our Charisma modifier times our Hit Dice to our Hit Point total.

container.child[Totals].field[tHP].value = container.child[Totals].field[tHitDice].value * hero.child[aCHA].field[aModBonus].value + container.child[Totals].field[tHP].value

I'm quite pleased with this as I'm currently at work without Internet access only on an iPhone and can't do major searches of the code base.
