Lua Item Upgrade basic value[1.2]

[Ascuas Funkeln]

Hello, i need help with this script.
What i want is, make this % upgrading every time from basic value, not from actual value.
Example:
Armor Value: 100
Upgrade per hit: 3%
Result from 0% to 3% is 105 instead of 103, cuz they calcuate all 3 level, and take value of actual lvl instead of basic 100.

@Edit
Ok thread to close i make it.

In this function:

local upgrading = {
  upValue = function (value, level, percent)
  if value < 0 then return 0 end
     if level == 0 then return value end
     local nVal = value
     for i = 1, level do
       nVal = nVal + (math.ceil((value/100*percent)))
     end
  return nVal > 0 and nVal or value
  end,

Change this line
nVal = nVal + (math.ceil((nVal/100*percent)))
to this
nVal = nVal + (math.ceil((value/100*percent)))
