Problem using set timer

[Gravestone]

I made this code to add a VIP account for 1 week. The timer should start when the object is added. To test, I set the timer to 1 second. The object doesn't get removed. Any help guys?

function addVIP (playerSource, commandName, accountName, type)  
    if accountName then 
  
        aclGroupAddObject (aclGetGroup("VIP"), "user."..accountName)  
        outputChatBox ("Account '"..accountName.."' has been succesfully made VIP (3 Weeks)", playerSource) 
        setTimer(removeVIP, 1000, 1) 
    else  
        outputChatBox ("No account name specified.", playerSource) 
        outputChatBox ("Correct syntax: /giveVIP [Account Name]", playerSource) 
  
    end 
end 
  
addCommandHandler ("giveVIP", addVIP) --ad 

The removing code:

function removeVIP (accountName) 
        aclGroupRemoveObject (aclGetGroup("VIP"), "user."..accountName) 
        outputServerLog("Account "..accountName.."'s VIP expired.") 
end 

For this, error in debugscript:

attempt to concatenate local 'accountName' (a nil value)

You need to add the arg here:

Try this :

function addVIP (playerSource, commandName, accountName, type) 
    if player and isElement(player) then  
        if accountName then 
            aclGroupAddObject (aclGetGroup("VIP"), "user."..accountName) 
            outputChatBox ("Account '"..accountName.."' has been succesfully made VIP (3 Weeks)", playerSource) 
            setTimer(removeVIP, 1000, 1,accountName) 
        else 
            outputChatBox ("No account name specified.", playerSource) 
            outputChatBox ("Correct syntax: /giveVIP [Account Name]", playerSource) 
        end 
    end  
end 
addCommandHandler ("giveVIP", addVIP)  
  
function removeVIP (accountName) 
    if accountName then  
        aclGroupRemoveObject (aclGetGroup("VIP"), "user."..accountName) 
        outputServerLog("Account "..accountName.."'s VIP expired.") 
    end  
end
