Variable number of skill bonus

[insaneurge]

I have been attempting to create an ability for a class to gain a bonus to a select number of skills at 1st level. However, all that is displaying is Skills: Choose, with no menu to choose from appearing. This is the script I have been attempting.

component.BaseSkill & Helper.ClassSkill

~Add +5 bonus to Class skill one
if (field[usrChosen1].ischosen <> 0) then
  field[usrChosen1].chosen.field[Bonus].value += 5
endif
~Add +5 bonus to Class skill two
if (field[usrChosen2].ischosen <> 0) then
  field[usrChosen2].chosen.field[Bonus].value += 5
endif

Somewhere I know there is a problem but I haven't been able to figure it out.

Second, is it possible to assign a variable number of choices to a script like this based on the number of class skill points a class receives plus Intelligence?
