on scrollbarLineDec
  Put field ButtonWidth into tBtnWidth
  put tBtnWidth + 1 into BtnWidth
  Put BtnWidth into field ButtonWidth
end scrollbarLineDec

on scrollbarLineInc
    Put field ButtonWidth into tBtnWidth
  put (tBtnWidth -1) into BtnWidth
  Put BtnWidth into field ButtonWidth
end scrollbarLineInc
