Alias player error

[MitnickP56]

Hi I have code for alias player, When I type /pma -- doesn't work.

    addEventHandler("onResourceStart", resourceRoot, 
        function() 
            executeSQLQuery("CREATE TABLE IF NOT EXISTS `players` (`serial` TEXT, `mute` TEXT, `alias` TEXT)") 
        end 
    ) 
      
    addEventHandler("onPlayerJoin", root, 
        function() 
            local serial = getPlayerSerial(source) 
            local name = getPlayerName(source) 
            local r = executeSQLQuery("SELECT `mute`,`alias` FROM `players` WHERE `serial`=?", serial) 
            if #r == 0 then 
                executeSQLQuery("INSERT INTO `players` (`serial`,`mute`,`alias`) VALUES(?,?,?)", serial, "no", name) 
            else 
                if r[1]["mute"] == "yes" then 
                    setPlayerMuted(source, true) 
                    outputChatBox(name:gsub("#%x%x%x%x%x%x", "").." has been muted by Console!", root, 255, 0, 0, true) 
                end 
            end 
        end 
    ) 
      
    addEventHandler("onPlayerQuit", root, 
        function() 
            if isPlayerMuted(source) then 
            else 
            end 
        end 
    ) 
      
    addEventHandler("onPlayerJoin", root, 
        function() 
            setAlias(source) 
        end 
    ) 
      
    addEventHandler("onPlayerChangeNick", root, 
        function() 
            setTimer(setAlias, 100, 1, source) 
        end 
    ) 
      
    function setAlias(source) 
        local find = true 
        local name = getPlayerName(source) 
        local serial = getPlayerSerial(source) 
        local r = executeSQLQuery("SELECT `mute`,`alias` FROM `players` WHERE `serial`=?", serial) 
        for i,v in ipairs(split(r[1]['alias'], 32)) do 
            if v == name then 
                find = false 
            end 
        end 
        if find then 
            executeSQLQuery("UPDATE `players` SET `mute`=?, `alias`=? WHERE `serial`=?", r[1]["mute"], r[1]["alias"].." "..name, serial) 
        end 
    end 
      
    function findPlayer(name) 
        if name then 
            for i, player in ipairs(getElementsByType("player")) do 
                if string.find(getPlayerName(player):lower(), tostring(name):lower(), 1, true) then 
                    return player 
                end 
            end 
        end 
        return false 
    end 
      
    local alias1 = "" 
    local alias2 = 0 
      
    addCommandHandler("pma", 
        function(p, _, t) 
            local target = findPlayer(t) 
            if target then 
                local serial = getPlayerSerial(target) 
                local r = executeSQLQuery("SELECT `mute`,`alias` FROM `players` WHERE `serial`=?", serial) 
                local spl = split(r[1]["alias"], 32) 
                for i, v in ipairs(spl) do 
                    if alias1 == "" then 
                        alias1 = v 
                        alias2 = alias2 + 1 
                    else 
                        alias1 = alias1..", "..v 
                        alias2 = alias2 + 1 
                    end 
                    if i == #spl then 
                        outputChatBox(alias1, p, 255, 255, 255, true) 
                        alias1 = "" 
                        alias2 = 0 
                    end 
                end 
            end 
        end 
    )
