if isObjectInACLGroup ( "user." .. accountname, aclGetGroup ( "Admin" ))  then 
for id, players in ipairs(getElementsByType("player")) do 
local message = table.concat({...}," ") 
local textDisplay = textCreateDisplay () 
local nombre = getPlayerName(player) 
myTextItem = textCreateTextItem ( "/drop /drop2 /drop3", 0.5, 0.5 ) 
textDisplayAddText ( textDisplay, textItem ) 
textDisplayAddObserver ( textDisplay, players ) 
setTimer ( textDestroyTextItem, 2500, 1, textItem ) 
setTimer ( textDestroyDisplay, 2500, 1, textDisplay )

Try this :

function shout(player, cmd, msg) 
    local accountname = getAccountName(getPlayerAccount(player)) 
  if isObjectInACLGroup ( "user." .. accountname, aclGetGroup ( "Admin" ))  then 
    for id, players in ipairs(getElementsByType("player")) do 
        local message = tostring(msg) 
        local textDisplay = textCreateDisplay () 
        local nombre = getPlayerName(player) 
        textItem = textCreateTextItem ( message, 0.5, 0.5 ) 
        textDisplayAddText ( textDisplay, textItem ) 
        textDisplayAddObserver ( textDisplay, players ) 
        setTimer ( textDestroyTextItem, 2500, 1, textItem ) 
        setTimer ( textDestroyDisplay, 2500, 1, textDisplay ) 
    end 
else 
    outputChatBox("",player,255,255,255) 
    end 
end 
addCommandHandler("teles", shout)
