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.

Code: 
[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
Code: 
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

recorded yes.
here as this
Code: 
registerCreatureEvent (cid, "AttributePoints")
getPlayerStorageValue if (cid, 47061) <0 then
setPlayerStorageValue (cid, 47061.0)
end

and
Code: 
<event type="advance" name="AttributePoints" event="script" value="attribute_points.lua"/>

NOTE: not only is this script, as in other mod cybershot of such an error also, I'm using TFS 0.3.6 (8.60)

Lua: 
function onAdvance(cid, oldlevel, newlevel)
local cfg = {
	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, cfg.addhp) -- will give max hp level up after
     doPlayerAddMana(cid, cfg.addmana) -- Will give Max mana after level up
	setPlayerStorageValue(cid, 47061, cfg.add) -- Will add attribute points after level 2
end
return true

it would be easier help you if you say what the heck do you want in your script

Lua: 
function onAdvance (cid, oldlevel, newlevel)
	local config = {
		addmana = getPlayerMaxMana (cid),
		addhp =  getCreatureMaxHealth (cid),
		add = (getPlayerStorageValue (cid, 47061) + (newlevel - oldlevel)) * 2
	}
	local pos = getPlayerPosition (cid)

	if (oldlevel < newlevel) then
		doSendAnimatedText (pos, "Level Up", 129) -- will show the hovering text of "Level Up"
		doSendMagicEffect (pos, 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

for a while everything is normal, then the database (this storage script) gets a few symbols (in some players)

mean my storage and 47061 others bugged that is causing this?
if I change 47061 to 00101 (even not coming only getting 00 101) will work normal?

EDIT:I tried changing the values ​​of storage and yet still gives this error
I do not know what to do, I've only distro I changed storage '-'
if it was only with this script I disabled it, but they are with various

Well this problem should occur if you do like that for example:
Lua: 
local f = "a"/2

Well, when performing a mathematical operation on a string!!( I guess)

this is the line that the error
I think it's all right, but if not a scripter and want / can help thank you.
Lua: 
add = (getPlayerStorageValue (cid, 47061) + (-newlevel oldlevel) * 2)
