it's because the event handler is linked to the window, the source would always be the window and the event would only trigger if you click on the window.

Try this:

      addEventHandler("onClientGUIClick",guiRoot,function(b) 
            if b ~= "left" then return end 
            if source == GUIEditor.button[2] then 
                guiSetVisible(GUIEditor.window[1],false) 
                showCursor(false) 
            elseif source == GUIEditor.button[1] then 
                local row,column = guiGridListGetSelectedItem ( GUIEditor.gridlist[1] ) 
                local SelectedSkin = guiGridListGetItemText ( GUIEditor.gridlist[1],row , 1 ) 
                if row == -1 then 
                    exports["TopBarChat"]:sendClientMessage  ("#0000FF* #FF0000You must select a skin first !",255,255,255,true) 
                    return 
                end 
                if getElementModel(localPlayer) ~= tonumber(SelectedSkin) then 
                    guiSetVisible(GUIEditor.window[1],false) 
                    showCursor(false) 
                    triggerServerEvent("onBuy",localPlayer,tonumber(SelectedSkin)) 
                else 
                    exports["TopBarChat"]:sendClientMessage  ("#0000FF* #FF0000You already have that skin !",255,255,255,true) 
                end 
            end 
        end)

i tried not work

[Jaysds1]

Oh, I misread your code.

You were checking if the text is -1 not if the selected row is -1.

Try my code again.
