Lua How to properly use getItemSpecialDescription ?

[Kakaher]

Hello everybody...

I hope someone can help me out here...
I just can't get this to work...

I want the script to check if the item on one of the players hand has a plus signal on its description...

Here is how the scripts looks like now:

local hand = getPlayerSlotItem(cid, CONST_SLOT_RIGHT)
local hand2 = getPlayerSlotItem(cid, CONST_SLOT_LEFT)
if (getItemSpecialDescription(hand):find('+')) or (getItemSpecialDescription(hand2):find('+')) then

I get this msg error:

[Error - TalkAction Interface]
data/talkactions/scripts/auction.lua:onSay
Description:
(luaGetthing) Thing not found

[Error - TalkAction Interface]
data/talkactions/scripts/auction.lua:onSay
Description:
data/lib/050-function.lua:269: attempt to index a boolean value
stack traceback:
data/lib/050-function.lua:269: in function 'getItemSpecialDescription'
data/talkactions/scripts/auction.lua:51: in function <data/talkactions/scripts/auction.lua:12>

Thanks a lot already for the help!

local hand = getPlayerSlotItem(cid, CONST_SLOT_RIGHT)
local hand2 = getPlayerSlotItem(cid, CONST_SLOT_LEFT)
if (getItemSpecialDescription(hand.uid):find('+')) or (getItemSpecialDescription(hand2.uid):find('+')) then

Try that, it's the most outlandish guess I can make here.

Still the same error = /

Does Anyone got an idea on how to use this properly?.. like maybe to set the description to a number to use for an item use countdown??

Like

13:00 You see a special flask.
 (Charges: 4)
ItemID: [7494].

Each time u use it will then count down the number till it reaches 1 or 0, w/e and then it'll removes the object....
