setPlayerMuted

[Chronic]

Hello, I have a question. setPlayerMuted is not working, any idea how to fix this?

curses = { "mta is gey" } 
  
addEventHandler ( "onPlayerChat", getRootElement(), 
        function (msg) 
                for i,v in ipairs(curses) do 
                        if msg == v     then 
                            if not ( getTeamName( getPlayerTeam ( source ) ) == "Staff" )   then 
                            setPlayerMuted ( source, true ) 
                            cancelEvent () 
                            outputChatBox ( "Flaming is not tolerated!", root ) 
                            elseif ( getTeamName( getPlayerTeam ( source ) ) == "Staff" )   then 
                            end 
                        end 
                end 
        end     ) 

and the error is:

Access denied @ 'setPlayerMuted'
