listname/livename not tallying correctly

[Bob G]

Hi again folks, this time working on a class special that adds a damage bonus equal to the number of sneak attack dice at a given level. At 11th level, the bonus doubles. I want the listname and livename to list the bonus as it scales in level. My code is

~only do this if we are the first copy
     doneif (tagis[Helper.FirstCopy] = 0)

~Set abValue
     if (#levelcount[LegeRogu] >= 11) then
     field[abValue].value += (field[xCount].value + 1) * 2
     else
     field[abValue].value += field[xCount].value + 1
     endif

~ Set the listname
     field[listname].text = field[thingname].text & " " & signed(field[abValue].value)

~ Set the livename
     field[livename].text = field[thingname].text & " " & signed(field[abValue].value)

The ability scales at every odd level, but the output in the class abilities tab and the Specials tab aren't calculating correctly. What did I screw up?
