Player is not defined anywhere on that function.

ok here is what I have so far, I fixed that issue only problem is the person receiving the message is not getting the GUI.. idk y, nothing happens.

---Client

function buildChatWnd () 
local row, col = guiGridListGetSelectedItem ( playerlist ) 
    if ( row and col and row ~= -1 and col ~= -1 ) then 
        playerName = guiGridListGetItemText ( playerlist, row, 1 ) 
        player = getPlayerFromName ( playerName ) 
        if ( player ) and ( player ~= getPlayerName ( getLocalPlayer() ) ) then --Check recheck 
            if not chats [ player ] then 
                chats [ player ] = { }   
                chats [ player ].window = guiCreateWindow(889, 491, 342, 298, getPlayerName ( player ), false) 
                guiWindowSetSizable(chats [ player ].window, false) 
                chats [ player ].memo = guiCreateMemo(14, 45, 312, 206, "", false, chats [ player ].window) 
                guiMemoSetReadOnly(chats [ player ].memo, true) 
                chats [ player ].edit = guiCreateEdit(14, 261, 227, 26, "", false, chats [ player ].window) 
                chats [ player ].send = guiCreateButton(248, 260, 78, 27, "Send", false, chats [ player ].window) 
                chats [ player ].close = guiCreateButton(314, 23, 18, 18, "X", false, chats [ player ].window) 
                addEventHandler( "onClientGUIAccepted", chats [ player ].edit, msgwino ) 
                addEventHandler ( "onClientGUIClick", chats [ player ].send, msgwino ) 
                addEventHandler ( "onClientGUIClick", chats [ player ].close, 
                        function ( ) 
                            _destroyElement ( chats [ player ].window ) 
                            chats [ player ] = nil 
                        end 
                            ,false 
                        ) 
            end 
        end

        guiSetText(chats [ player ].memo, oldText)

        guiMemoSetCaretIndex(chats [ player ].memo, string.len(oldText)) 
        triggerServerEvent("sMsg", localPlayer, player, newText)

end

---get the message who ever you sent it to.

No errors?

[Dice]

Nope, only thing is the other person only gets the message if the window with you is already open, if he doesn't have a little chat window open, and I send the person a message, it will not open the chat window on the targetplayers side, like I said unless his chat window is already open.

[Dice]

Guessing it has to do with line 2-5 on the first client I showed =\ don't know where else to put it.
