Lua attempt to perform arithmetic on a string value - Help

[_Aion_]

Hello I would like to know how can I fix this problem>> attempt to perform arithmetic on a string value <<
've changed my distro several times, looked at the lib and I think it's all normal.
the database was to be a numbers example: 31231321454 and is getting '* Y (some strange symbols)
appears in this distro.

[25.12.2011 16:00:15] [Error - CreatureScript Interface]
[12/25/2011 16:00:15] data / creaturescripts / scripts / attribute_points.lua: onAdvance
[12/25/2011 16:00:15] Description:
[12/25/2011 16:00:15] data / creaturescripts / scripts / attribute_points.lua: 6: attempt to perform arithmetic on a string value
[12/25/2011 16:00:15] stack traceback:
[12/25/2011 16:00:15] data / creaturescripts / scripts / attribute_points.lua: 6: in function <data/creaturescripts/scripts/attribute_points.lua:1>

Here is the script

function onAdvance(cid, skill, oldlevel, newlevel)
	if skill == 8 then
		if oldlevel < newlevel then
    local addmana = getPlayerMaxMana(cid)
    local addhp = getCreatureMaxHealth(cid)
	local addattribute = (getPlayerStorageValue(cid, 47061)+(newlevel-oldlevel)*2) -- this is the line that corrupts the database and displays this error "attempt to perform arithmetic on a string value"
    doSendAnimatedText(getPlayerPosition(cid), "Level UP", 129)
    doSendMagicEffect(getPlayerPosition(cid),math.random(28, 30))
    doCreatureAddHealth(cid, addhp)
    doPlayerAddMana(cid, addmana)
	setPlayerStorageValue(cid, 47061, addattribute)
		end
	end
	return true
end

this is not just the script that this error, even in the MOD cybershot an error like this, I would like to know how to solve this problem because I'm having a lot of headaches.

Thank you.

sorry for my bad English

try

local check = tonumber(getPlayerStorageValue (cid, 47061)) or 0
add = (check + (newlevel-ldlevel) * 2)

try

local check = tonumber(getPlayerStorageValue (cid, 47061)) or 0
add = (check + (newlevel-ldlevel) * 2)

even though it still gives the same error

 

[Shinmaru]

is there another script that sets a value to key '47061' other than this script?? I assume there is since, you never check is 47061 is a nill, so there must be another script setting up a value that is not an integer.

 

[_Aion_]

there was for normal functioning, but is giving this error and even putting it in another storage the same error.
being that has no string = "test" in the script, and in several script is giving this error even in the MOD (REP) of the cybershot.
I do not know what I can do and can not disable these scripts because they are very essential for my OTServ.

Did you registred this even on login.lua? If not register it and it may work!

 

[_Aion_]

the error is not this script, it is one of.
all recorded this normal, he works for a time deposed the database "corrupt" instead of getting numbers is getting a few symbols.

Like Doggynub said before, this error happens when you try to perform a mathematical operation in a string

function onAdvance (cid, oldlevel, newlevel)
    local config = {
        addmana = getPlayerMaxMana(cid)
        addhp = getCreatureMaxHealth(cid)
        add = (getPlayerStorageValue (cid, 47061) + (newlevel-oldlevel) * 2)
    }
    if oldlevel < newlevel then
        doSendAnimatedText (getPlayerPosition (cid), "Level Up", 129) - will show the hovering text of "Level Up"
        doSendMagicEffect (getPlayerPosition (cid), math.random (28, 30)) - will show the range of fireworks
        doCreatureAddHealth (cid, config.addhp) - will give max hp level up after
        doPlayerAddMana (cid, config.addmana) - Will give Max mana after level up
        setPlayerStorageValue (cid, 47061, config.add) - Will add attribute points after level 2
    end
    return true
end

Your script should now work

If you have more scripts with this problem, you can add me on MSN(check my profile) and I'll help you there, it's faster and easier
