attempt to perform arithmetic on local 'timeleft' (boolean value)

[almafa123]

Hello

function timerUnjailPlayer(jailedPlayer)
    local timeLeft = getElementData(jailedPlayer,"jail->Jailtime")
    timeLeft = timeLeft - 1
    if tonumber(timeLeft) <= 0 then
        dbPoll ( dbQuery( connection, "UPDATE accounts SET jailedtime='0', jailed='0' WHERE id='?'", getElementData(jailedPlayer, "acc.accountID")), -1 )
        setElementData(jailedPlayer, "jail->Jailtime", 0)
        setElementData(jailedPlayer, "jail->Timer", nil)
        setElementData(jailedPlayer, "jail->Time", 0)
        
        setElementPosition(jailedPlayer, 1519.7177734375, -1697.8154296875, 13.546875)
        setPedRotation(jailedPlayer, 269.92446899414)
        setElementDimension(jailedPlayer, 0)
        setElementInterior(jailedPlayer, 0)
        setCameraInterior(jailedPlayer, 0)
        toggleControl(jailedPlayer,'next_weapon',true)
        toggleControl(jailedPlayer,'previous_weapon',true)
        toggleControl(jailedPlayer,'fire',true)
        toggleControl(jailedPlayer,'aim_weapon',true)
        outputChatBox("#87D37CKiszabadítottak a börtönbõl! Legközelebb ésszel viselkedj!", jailedPlayer, 0, 0, 0,true)
    else    
        setElementData(jailedPlayer,"jail->Jailtime",timeLeft)    
        dbPoll ( dbQuery( connection, "UPDATE accounts SET jailedtime=? WHERE id='?'",tonumber(timeLeft), getElementData(jailedPlayer, "acc.accountID")), -1 )
    end
end    

Warning: /admin/codeserver.lua:822: Bad argument @ 'getelementdata' [Expected element at argument 1]

Error: /admin/codeserver.lua:823: attempt to perform arithmetic on local 'timeLeft' (a boolean value)

Please help me.

Thanx.

If there is no data available it will return false. false is a boolean value - obviously you can't do math with a boolean.

Make sure there are no typos first of all, otherwise make sure it returns a valid value before trying to do math with it.

This seems like the function timerUnjailPlayer receives a nil instead of the player on parameter jailedPlayer (hence error at line 822) and that results in no element data being collected, creating an arithmetic error on line 823 when trying to compare no data to a number.
