Bad argument @ 'setElementData'

[FSXTim]

Hello,

I got the following error in the serverside script: Bad argument @ 'setElementData' [Expected element at argument 1, got string '0'] (Zeile 5)

clientside:

function unbannB (state) 
    if state == "left" then 
        if source == GUIEditor_Admin_Button[10] then 
            local nick = guiGetText(GUIEditor_Admin_Edit[9]) 
            triggerServerEvent("unbannP", lp, nick) 
        end 
    end  
end 
addEventHandler("onClientGUIClick", getRootElement(), unbannB) 

serverside:

function unbannP (nick) 
    local name = MySQL_GetString("Bann", "user_data", nick) 
    if name then 
        local admin = getPlayerName(source) 
        setElementData(name, "Bann", "0") 
        outputChatBox ("#FFFFFF|INFO| "..admin.." #FF3030hat #FFFFFF"..nick.." #FF3030entbannt!", getRootElement(), 205, 0, 0, true)     
    else 
        local player = source 
        outputChatBox ("Der Spieler existiert nicht!", player, 255, 48, 48) 
    end 
end 
addEvent("unbannP", true) 
addEventHandler ("unbannP", getRootElement(), unbannP)
