Creating Power Point pool in SWADE

[Gumbytie]

Beasts & Barbarians has an edge "Temptress". Gives the character boost/lower trait Power with its own power point pool. In Deluxe SW it is Charisma + 1/Rank Power Points. And my edge code worked and is this:

#trkmax[trkPower] += ((herofield[acRank].value + 1) + #traitbonus[trCharisma])

var PPoint as number
PPoint = ((herofield[acRank].value + 1) + #traitbonus[trCharisma])

field[livename].text = field[thingname].text & " (PP: " & PPoint & ")"

We have no Charisma in SWADE so the edge is modified to, Persuasion + 1/Rank Power Points. So tried this code but no avail:

#trkmax[trkPower] += ((herofield[acRank].value + 1) + #traitprof[skPersuadeSWADE])

var PPoint as number
PPoint = ((herofield[acRank].value + 1) + #traitprof[skPersuadeSWADE])

field[livename].text = field[thingname].text & " (PP: " & PPoint & ")"

So I need to pull the dice amount for the Persuasion skill and obviously doing it wrong Any suggestions?
