Lua Upgrade script help

[Santi]

I need a bit of help here, since I don't want to change the script drastically, I need to know if theres any alternative that I don't know.

function isArmor(uid) -- Function by Mock the bear.
    if (getItemInfo(uid.itemid).armor ~= 0) and (getItemWeaponType(uid.uid) == 0) then
		return true
	end
	return false
end
function isShield(uid) -- Function by Mock the bear.
	uid = uid or 0
	if getItemWeaponType(uid) == 4 then
		return true
	end
	return false
end
function isBow(uid) -- Function by Mock the bear.
	uid = uid or 0
	if getItemWeaponType(uid) == 5 and not isItemStackable(uid) then
		return true
	end
	return false
end

function Santirox() -- function by Santi
local t = {
[1] = '10%',
[2] = '20%',
[3] = '30%',
[4] = '40%',
[5] = '50%'
}
for k, v in pairs(t) do
    if getPlayerStorageValue(getItemIdByName(itemEx.uid)) == k then
       if getPlayerStorageValue(getItemIdByName(itemEx.uid)) < 2 then
          return doItemSetAttribute(itemEx.uid, 'description', "Tu arma ha sido upgraded " .. k .. " vez, con un total de " .. v[1] .. "")
       else
           return doItemSetAttribute(itemEx.uid, 'description', "Tu arma ha sido upgraded " .. k .. " veces, con un total de " .. v[1] .. "")
       end
    elseif getPlayerStorageValue(getItemIdByName(itemEx.uid)) > 5 then
           return doItemSetAttribute(itemEx.uid, 'description', "Tu arma ha sido upgraded " .. k .. " veces, con un total de  " .. v[1] .. ", y ha llegado a su maximo")
    end
end
return true
end

function onUse(cid, item, fromPosition, itemEx, toPosition)
if isInArray({1,2,3},getItemWeaponType(itemEx.uid)) then
   doItemSetAttribute(itemEx.uid, 'attack', (getItemInfo(itemEx.itemid).attack*10)/100)
   setPlayerStorageValue(cid, getItemIdByName(itemEx.uid), getPlayerStorageValue(getItemIdByName(itemEx.uid))+1)
   doRemoveItem(item.uid, 1)
   Santirox()
elseif isArmor(itemEx) or isShield(itemEx.uid) then
       doItemSetAttribute(itemEx.uid, 'defense', (getItemInfo(itemEx.itemid).defense*10)/100)
        setPlayerStorageValue(cid, getItemIdByName(itemEx.uid), getPlayerStorageValue(getItemIdByName(itemEx.uid))+1)
        doRemoveItem(item.uid, 1)
        Santirox()
elseif isPlayer(itemEx.uid) or not (getItemWeaponType(itemEx.uid) or getItemWeaponType(itemEx.uid) > 5) or (getItemWeaponType(itemEx.uid) == 0 and not isArmor(itemEx)) or itemEx.itemid == 0 or itemEx.type > 1 or isItemStackable(itemEx.uid) then
       return doPlayerSendCancel(cid, "Sorry not possible")
end
return true
end

The error I'm getting is:

[19/01/2011 13:55:54] [Error - Action Interface]

Any type of help is appreciated!
PS: I need to know if my function is okay too, Im new at creating functions at LUA

Wtf, getPlayerStorage parameters don't make sense at all.

yes they do all he is missing is "cid" look:

getPlayerStorageValue(getItemIdByName(itemEx.uid))

it should be:

getPlayerStorageValue(cid, getItemIdByName(itemEx.uid))
